`rule_runner.do_not_use_mock` has issues with call-by-name rule calls

[ndellosa95]

Describe the bug
I have a plugin where I use the call-by-name syntax in certain spots where I know the name of the rule call (primarily calls to other rules in the same plugin). I'm working on unit tests for said plugin, and I've run into this when attempting to use rule_runner.do_not_use_mock on these rules that are invoked by name.
