Make recover_streaming_appliers_if_not_recovered() public

Browse Source 
The method is needed by GRP provider to recover SR transactions
after becoming connected to the cluster. The SST code path does
not get always executed, and the view change hander is too late
in codepath as the GRP may start applying events without
delivering primary view first.
