Fix flaky test: MergeRequestReferenceFilter URL reference for a commit

The test was failing intermittently because the Banzai filter's project context didn't match the merge request's owning project.

The test creates two projects:

project (line 8) - default filter context
mr_project (line 269) - owns the MR being tested

When reference_filter is called without explicit project parameter, it uses project from line 8. The filter's reference cache can't find the MR (wrong project scope), returning the URL unchanged.

Fix: Pass mr_project as the project context to reference_filter.
