Replication
Description
In SERVER-39950 we merged some redundant code paths between sync tail and initial sync. In doing so we lost some optimizations which affect the insert_vector test performance on secondaries.
The largest effect is probably the extra copy of the batch here
But also note this pre-allocation may not be useful after removing that
whereas pre-allocation here may be helpful
