[Sync] Remove NOTREACHED that causes flakes in Android tests.

[Sync] Remove NOTREACHED that causes flakes in Android tests.

It doesn't seem to actually need to be there. The comment even says that
branch can happen and doesn't seem to mention it being a problem.

Specifically, I have seen this cause SyncTest.testRename to flake
locally.

Pavel, PTAL. We talked about this a long time ago but I must have forgotten
about it before changing anything. As far as I can tell this branch isn't
actually a problem and shouldn't have a NOTREACHED.
