compound_wildcard_index_insert.js generates DuplicateKey errors during execution resulting causing us doing performance analysis on a workload that is not representative of likely customer workloads.

With vectored inserts, these DuplicateKey errors trigger a fallback where we insert documents one by one and we're getting an artificial signal of bad performance due to the behavior of this workload.

We should fix is to make it more representative of what users would actually do.
