Crashes due to chapter URN absence in metadata

[defagos]

Is there an existing issue for this?

• [X] I have searched existing issues and found no similar bug report.

Description of the problem

Checking SRF News crash reports with Xcode we found a few issues related to Pillarbox. These should be further investigated.

This issue is related to a force unwrap assuming that a chapter matching a chapter URN is always available in a media composition. Well, it seems that sometimes this breaks for some reason.

Crash logs are attached to this issue.
