Revert of Quit the message loop by default in ShellConnectionLost when ApplicationRunner is used

Revert of Quit the message loop by default in ShellConnectionLost when ApplicationRunner is used (patchset #2 id:20001 of https://codereview.chromium.org/1819063002/ )

Reason for revert:
Looks like to made the mojo_apptests go red. I think this is also making MUS tests fail?
