/**
* Initial sync runs in several phases - the first 3 are as follows:
* 1) fetches the last oplog entry (op_start1) on the source;
* 2) copies all non-local databases from the source and fetches operations from sync source; and
* 3) applies operations from the source after op_start1.
*
* This test renames a collection on the source between phases 1 and 2, but renameCollection is not
* supported in initial sync. The secondary will initially fail to apply the command in phase 3
* and subsequently have to retry the initial sync.
