Don't recheck DeviceListener until after initial sync is finished

Browse source 
Each recheck caused a GET to account data to see if the master key
exists if done before the initial sync, which is unnecessary here.
This just makes it wait until the initial sync is done to recheck.

Fixes https://github.com/vector-im/riot-web/issues/13279
