Collection creation fails with NamespaceExists (code 48) after a preceding collection drop in mongoshell in test suite sharded_causally_consistent_jscore_passthrough. Failure happens only when additional options are passed to the create command.

Of cause, tests that issue a similar sequence could be excluded from the affected test suites, but it is not obvious why such code sequences should not be permitted in sharded_causally_consistent_jscore_passthrough test suite and others.
