/**
* 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
* 3) fetches and applies operations from the source after op_start1.
*
* Between phases 1 and 2, this test updates array fields and subdocument fields with both the
* "update" and "applyOps" commands on the source, then replaces the array/subdoc fields with
* strings. The secondary will fail to apply the update operation in phase 3 but initial sync
* completes nevertheless. The absence of the array/subdoc on the source indicates that a later
* operation has replaced the field, so the target is free to ignore the failed update operation.
