Remove ImsConfigTracker#onBindInput precondition

It is expected the onIntialize() is called before onBindInput(), however
it's not precisely known why onBindInput() is being called prior to onIntialize().
Once possibility is it could be that onDestory() is being called
and init was skipped and call made it to onBindInput().

Replacing precondition with an early return should be safe here.
