There is no need to use the main queue just for perform selector.
We were using the main queue to queue up a perform selector and then the code
[self sendStoredCrashReports] was immediately doing a dispatch_async.
This unnecessary thread switching is not needed.
We simplify the above logic and use dispatch_after to queue the block on
the
internal queue after a delay
Note that main queue is typically more loaded and it is better for
non-UI code
to not use the main queue. This may also help improve crash log upload.
This change also switches from @synchronized to dispatch_once as that is
faster
