* Monkey is hitting this fairly often
* Multiple fixes that are all good
* We were launching LoadAccountsTask twice
* Don't use a managed cursor for the inner accounts cursor - always
close it manually by calling changeCursor(null) and letting the
MergeCursor handle its sub-cursors.
* Add isCancelled() check
* When replacing adapter, be sure to close cursor
