* Remove some very old code that updated the Account in the database
when finishing an EAS FolderSync. The old code saved away the entire
Account structure using getContentValues(), which has long been recognized
as dangerous, since the data being saved might be stale.
* In this case, we were clearing the INCOMPLETE flag in another thread, but
FolderSync was saving away the old value (with INCOMPLETE set) along with
all of the other columns.
* Ironically, the old code is entirely obsolete, so the solution is to
simply remove the update call.
