Make Android back work correctly in Elderberry.

Make Android back work correctly in Elderberry.

Prior to this if you have previously ever launched the tabbed
mode of Chrome, clicking on the back button of an elderberry
tab would refocus Chrome instead of the app that launched it
(only for versions launched with NEW_TASK).

The only thing I don't understand is why this doesn't separate regular
CustomTabActivity into a new task stack. Is it because of
relinquishTaskIdentity?
