Matthew Barnes c5265294a3 Avoid idle callbacks in EMailBackend initialization.
If the migration phase has to show a dialog the idle callback for
intializing mail stores will run too soon.  Instead, hook it onto
the EShellBackend start() method.

Migration code can initialize mail stores early if it needs to.
