Revert 287680 "mojo: terminate apps if the shell goes away"

These tests started consistently failing: ConnectBasicNetwork, ConnectInvalidServiceNetwork.

> mojo: terminate apps if the shell goes away
> 
> Each application <> shell connection is represented by a ShellImpl instance
> on the shell side. This CL makes the Application watch its ShellPtr for pipe
> errors so it can Quit() itself if the shell goes away (shell loop destroyed).
> 
> mojo_shell_tests starts using a new method to terminate all shell connections
> in this CL, and waits afterward until KeepAlive quits the loop signifying that
> all apps are gone. This is done prior to destroying the shell MessageLoop so
> that the test ensures apps have all died before the next test. In the future
> it would be a test failure if this wasn't a no-op, but we have things in the
> shell that don't quit themselves right now.

> The shell itself won't wait around for apps to die (as of this CL), but
> ~MessageLoop will still send the message to Application sides that will quit.

> ** NOTE ** This does not require an app build target to explicitly add magic
> *.cc files to their sources.  It requires selecting an appropriate
> mojo_application_{chromium, standalone} library akin to mojo_environment_*.
> We can possibly combine these two in the future.
