Fix flake in testMobileDataAlwaysOn

Browse Source 
The internal structure backing getAllNetworks is updated after
invoking lost callbacks, so the test needs to wait for the handler
to be idle before calling getAllNetworks.

Also avoid assertions in finally clauses, as it causes confusing
error messages.
