/**
* 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.
*
* This test updates and deletes a document on the source between phases 1 and 2. The secondary will
* fail to apply the update operation in phase 3 but initial sync completes nevertheless. The
* absence of the document on the source indicates that the source is free to ignore the failed
* update operation.
