Throw an exception if a package is created without setting the author's email
Return trashed models with morphTo() if told so on non-eager queries (fixes #4870)
Fix logic around marking services resolved or not

If you app->extend an object after it's been bound but before it's
been resolved, it will be initialized right away. The solution is
to just check if an object has actually been resolved rather than
if it's bound.

A related issue that can also be solved as a part of this is that
you can't extend deferred services. This has also been fixed.
