Initially we did this to avoid a duplicated task right after the migration from Fennec. We'd end up
with the original task from Fennec and the new one from Fenix; with the Fennec task still showing
Fennec in the app switcher, but launching Fenix once selected.
Anyhow, now on Android 11 this causes the Fenix task to get duplicated. The simple fix is to not
do any of that anymore. This may re-introduce the problem with the Fennec migration, but:
* We are at 100% rollout for quite some time. There are still users migrating, but the impact
of the bug is much lower.
* The bug after the migration was only temporary. This bug here is happening every time you
launch Fenix. So I'd rather fix this than a possible inconvenience right after the migration.
This also simplifies how we do this. We're no longer creating instances of `DesktopFolder` class
nor creating copies of BookmarkNodes just to display root titles correctly for the 'edit folder' UI.
This also switches to a simpler bookmarks query API ('getBookmark') which doesn't fetch
children. We don't need 'children' for this dialog, and so don't need to do the extra work.
Note that the "Share" title is still constrained to start at the end of the
close button - I don't know why the previous extra constraint was causing the
differing behavior in LTR and RTL, but this seems to fix it.
