This _removeLegacyTimeseriesBucketingParametersHaveChanged argument to collMod should only be used internally, and is rejected when authorization is enabled.
However currently the fuzzer tests (jstestfuzz) run on clusters configured without access control enabled and thus are able to run those internal commands.
We should skip this command from fuzzer tests, as otherwise they can create spurious inconsistencies and/or trigger tripwire assertions.
