Harmonize MET settings for CA vs RecExCommon ARTs

The ARTs for ComponentAccumulator vs. RecExCommon q-test comparisons have been reporting some differences in the containers that are present for MET: some monitoring/validation containers were present from CA but not RecExCommon.

This turned out to be due to an inconsistency between the flag settings used for these tests. This MR turns on the flag which also writes these containers out for RecExCommon within these tests, which should bring this into agreement. Note that these containers should be getting reconstructed (normally for monitoring purposes) in all cases, but not actually written to the AOD unless the flags are set.

Tagging @elmsheus, @goetz, & @mhodgkin, so they're aware why this will disappear from the discrepancy list.
