George Kalpakas c5d0b76e29 refactor(service-worker): avoid unnecessary writes to cache when version fails (#43680)
When an app version is detected as broken, the SW calls the
`Driver#versionFailed()` method. Previously, this method would in turn
call the `Driver#sync()` method, which writes some metadata about the
SW's state to the `ngsw:/:db:contol` cache. More specifically,
`Driver#sync()` persists info about all known app versions, which one is
the latest and also what version each client is assigned to.

However, no relevant info is changed inside `Driver#versionFailed()`, so
the call to `Driver#sync()` is redundant (since there are no changes
that need to be synced with the cache). This is a left-over from
before #43518, when `Driver#versionFailed()` used to update version
assignments and thus did require synchronization with the cache.

This commit removes the redundant `Driver#sync()` call to avoid an
unnecessary write to the cache.
