Couchbase Lite 1.2 CBLReplication Pull stuck at status 3 in airport mode

@pvaghasi

It does times out but after long time i suppose. The problem is if 1. replication started running when there is no internet 2. after 8 retries, replication is now will retry after 256 seconds,3. Internet is back 4. Still replication is going to wait for 256 full seconds.

Ideally when there is change in reachability replication should immediately retry rather than waiting

Raised #1326 for this one.
