WIP: fix: fail safe when portlet lacks title

[apetro]

In case where portlet.title undefined don't consider that portlet a filter match on title but also don't exception out the whole filtering attempt.

The app directory data should be good. This should never be a problem. But if the data is bad in this way, the consequence should be contained to the handling of that one bad record.

• [ ] Manually fix the semantically incorrect automatic CHANGELOG merge

The automatic CHANGELOG merge doesn't correctly conceptually merge, in that it would document this change into the wrong release.
