Fix intermittent test failure caused by race condition

First public pull request 😬

There's an intermittent integration test failure when you use multiple test threads (at least for me on a mac). I narrowed it down to two tests each spawning a process using `Command` which then try to compile the same file at the same time. If the timing doesn't work out, they both try to compile, and then one process runs `clean` before the other can run the executable - causing a panic.

![Screenshot 2019-04-07 at 19 54 55](https://user-images.githubusercontent.com/3453268/55688324-20520980-596f-11e9-8474-5215d61a4387.png)

You can prevent it from happening by running with a single thread (`cargo test -- --test-threads=1`), because the `Command` blocks. That's not a particularly good solution though because it's not something you can configure in `Cargo.toml`.

I considered making the affected tests just run serially, but it occurred to me that this could also happen if someone accidentally runs rustlings in watch mode in two terminals without realising it. I wound't consider this that unlikely given it's a tool for learning.

I fixed it by ensuring that the executables made from separate processes don't conflict by appending a process id to the output executable name. I also extracted the commands into a single file next to `clean` so that we don't have to repeat the generated file name everywhere and risk missing something.

Stop run from panicking when compile fails

Currently if you use the `rustlings run` command and your program fails to compile, rustlings will panic while trying to exit.

First I've added a couple of integration tests to cover this case, which also meant moving a few tests so that the new fixtures didn't cause `verify_all_success` to fail.

Then I noticed that the existing integration tests that test for failure pass even when rustlings panics, preventing the new tests from failing. I've updated the integration tests to distinguish between when rustlings has failed in the way that we want (exit code 1) rather than a panic (exit code 101).

Finally I fixed the actual panic, which was just caused by unwrapping when rustlings should probably be exiting cleanly.

fix watch command path execution

@hades32 @guttume could you test whether this works on windows by checking out the branch locally and running `cargo run watch`?

I would have liked to write some tests for the vercomp function I
introduce, but there doesn't seem to be any CI setup yet?

Kyle Isom 9fc4a83987 Be nicer when rustlings isn't run from the right directory.
Before, rustlings would panic if it wasn't in the right directory. It
took me a minute to figure out why, and this wasn't my first intro to
Rust. It would probably help new users if they saw a helpful message
instead of a stack trace.

seems like i forgot that you actually need to run executables created
with `rustc --test`! this also reworks the "test1" exercise a bit
