Selecting a tab while in Multiselect would add a different decoration to the one
already set for the last tab opened and this would confuse users.
Let's avoid this.
Removed now obsolete feature flag and tests.
Removed obsolete swipe refresh state from BookmarkFragmentState
Also adapted tests and remove obsolete ones.
Upgrades to A-C 69.0.20201203202830 and addresses breaking changes:

- SearchUseCases accept parent session ID instead of session itself
This PR builds on [AC##9024][1], and implements setting the Nimbus endpoints from [a secret set at build time][2].
For production use, this requires a secret named `nimbus_url` to be put into CI.
Note: Nimbus is currently behind a feature flag.
If developers wish to use a Nimbus server for local development, you can set the url by adding an entry into local.properties, e.g.:
```
nimbus.remote-settings.url=https://settings.stage.moz4ws.net
```
Without setting server, Nimbus will be able to function, except no experimental definitions will be fetched, and features under experiment will be configured as if not enrolled in the experiment.

This doesn't fix the underlying issue of #16435, but a symptom we have seen quite often in different
situations: When the ExternalAppBrowserActivity is not linked to a tab anymore then it falls back
to displaying a (partially broken) browser UI. With multiple browser activities at the same time
sooner or later we crash with a "display already acquired" error because both activities try to
render the same tab.
