When running resmoke with --runAllFeatureFlagTests --disableUnreleasedIFRFlags, tests tagged with unreleased IFR feature flags are still selected to run, even though the flags are disabled on the server. This means the test executes against a server where the feature is off, leading to unexpected failures.

See logs for update_cmd_mongos_slow_query_log.js running even though it was tagged with featureFlagUnifiedWriteExecutor which is currently an unreleasedIFRFlag

This is also true for non passthrough tests. The following still runs lookup_unwind_sbe_pushdown.js even though the test is tagged with featureFlagSbeEqLookupUnwind which is a still an in development IFR flag.
