(#4815) Fix PDQ phpstan issues

[bkline]

In pdq_cancer_information_summary/src/OrphanCleanup.php:

• remove line of code inadvertently copied from another method
• reassure PHP (and phpstan) that we have the the right interface for invoking deleteRevision()

Closes #4815

The "phpstan for PDQ" PR -- #4923

The change looks good to me, and I've done some simple testing.
But against the bigger picture of the CDR going away, that's been the extent of it.

(i.e. I've not asked Bob to send edited summaries.)

I think we are actually going to merge this during the feature branch work. Basically it should get tested with Summary transforms...

[welshja]

To test, we'll need to get this onto an ODE and then run the new loader to confirm that things work as expected and all summaries are loaded with no crazy errors/fires/natural disasters. (Orphaned cleanup part of the loading process runs without issue.)

@jfrank-nih to check with @blairlearn in terms of any testing steps to review on the ODE where it is currently deployed.
