Merge pull request #1290 from wordpress-mobile/issue/1285-null-host-setupblog

fix #1285 npe in setupblog
fix #1321
fix #1320: onPostClicked can be called from a separate thread,
this thread can run after the activity onStop() and in this case,
commiting the fragment will crash the app.

Replacing a call to `commit()` by a call to `commitAllowingStateLoss()` in
this particular case, will avoid a crash but also lose the fragment state:
the selected comment or post won't be recreated.
