fix: prefix -run in GoTestXXX with '-test' (#435)

When providing custom arguments (`:GoTest-n -a -test.timeout=5s`), the
resultant command will be:

`go test <package> -args -test.timeout=5s -run=<exp>`

Since `-run` is after `-args`, the `-test.` prefix is required to be
properly detected. According to `go help testflags`, all test commands
are recognized with this prefix.
