Reduce blank widget headers

Make sure to not call updateAppWidget if either the folder name
or account name is empty (updateAppWidget causes the app widget state
to be persisted)

If an empty string is passed to configureValidAccountWidget, don't
update the remote view, as the remote view should have valid data

Log the cases where empty strings are passed to these calls to
track down these cases.
