Fan Zhang 76dbb21cb5 Protect against invalid authority in account sync pref.
Some apps might contain account synclets with empty authority. Settings
UI should protect against this type of synclets. Otherwise clicking on
these synclets will crash.

(Also removed some strings that are no longer needed)

Change-Id: I364b45fc67679aa287ff1e04e6f5ac749116543a
