[client-sync] Sync accounts when app comes back online

Browse source 
Summary:
Given that we backoff exponentially in the sync loop when we encounter
RetryableErrors (e.g. network errors), if the app goes offline and
reaches the maximum retry backoff of 5 minutes, and if then the app comes
back online, in the worst case, the sync loop will idle for 5 minutes before trying to
sync, which is undesireable.

To mitigate this, everytime we come online we can wake all of the sync
workers. This shouldn't have any adverse effects
