Updated filename for iOS, added token description (home-assistant#3131)

Variour · fabaff · commit 3a363b2e3dad · 2017-08-04T08:34:20.000+02:00
The filename to extract the token from the iOS backup has the USERID in the front ({USERID}_mihome.sqlite). A file without the {USERID} existed as well, so i think the clarification is needed.
In addition i added a description of how the token looks so one knows what to look for.
