Forward Port: Volume button seek on screen off [2/2]

bluetooth: Show a refresh icon on the select devices screen

The refresh menu is hidden behind an overflow which is
pointless. This patch shows the refresh icon if there is
enough room.

TrustedCredentials: Don't crash when the activity is paused

If you press Settings -> Security -> Trusted Credentials, then press
 back before the loading finishes, the loader async task will still
try to dereference the activity which will cause an NPE.

This patch fixes that by getting and holding a reference to the
context in the beggining and bailing early if it is null.
