Dave Townsend 7e72af1d6f Bug 1087966: Fix tab detach in e10s windows. r=mconley
When swapping docshells we also have to swap any properties on remote-browsers
that are cached from the content process. This includes things like the
remoteWebNavigation etc. which in turn cache content information. Some of
these also maintain message listeners that we have to switch to the new browser
and message manager.
