Since the Call API's callbacks are now fired from handlers, they end up
changing the order in which the callbacks from the Phone and Call API's
are fired. To preserve the below ordering, we move the call removal from
Phone's db to after all the onCallDestoryedcallbacks have executed.
1. Call->onStateChanged
2. Call->onDetailsChanged
3. Call->onCallDestroyed
4. Phone->onCallRemoved
