Fix MongoDB flaky DBM test

[bojbrook]

What does this PR do?

Fixes the mongoDB flaky test when DBM propagation is set to full. Example error.

 AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
    + actual - expected
    
    + "dddb='admin.%24cmd',dddbs='test-mongodb',dde='tester',ddh='127.0.0.1',ddps='test',ddpv='11.7.5',ddprs='admin',traceparent='00-693cf4dc00000000162f8b1eda59e22b-162f8b1eda59e22b-00'"
    - "dddb='test.4cd4a2caadc196e5',dddbs='test-mongodb',dde='tester',ddh='127.0.0.1',ddps='test',ddpv='11.7.5',ddprs='test',traceparent='00-693cf4dc0000000036365d6198aac05c-36365d6198aac05c-01'"

The value discrepancy was caused by MongoDB emitting isMaster commands, which were being traced but did not match the values included in the SQL comment. This PR updates the tests to assert against the values produced by injectDbmComment.

Motivation
