Creating TLOG with pure multiple PULL replica, leading to 0 doc count

With only PULL replica whenever we create a new TLOG as leader fresh replication happens, resulting in flushing the older indexes from existing PULL replicas

Steps to replicate:

1. Create 1 NRT or 1 TLOG replica as leader with multiple PULL replicas
2. Index few documents and let it replicate in all the replicas
3. Delete all the TLOG/NRT replica leaving PULL types
4. Create a new TLOG/NRT as leader, once recovery completes it replaces all the older indexes

In ideal scenario it should have replicated from any one of the PULL replicas that has latest indexes after that TLOG/NRT replica should be registered as leader
