Describe your changes

Some items on Plex store the MBID in the guid field in the Metadata response, not in the Guid field. This change checks the guid field as a fallback if the Guid field is not set.

This seems to be very rare. I've only found it on one release in my library and it fixed itself after clicking "Fix Match..." and matching it again.

Example of an item with the MBID in `guid`

Hey @owendaprile can you take a look at the review?

Not sure if I'm going crazy but I don't see one 😕. Or do you just mean to submit mine?

@owendaprile I never hit submit 😅 oops

Some items on Plex store the MBID in the `guid` field in the `Metadata`
response, not in the `Guid` field. This change checks the `guid` field
as a fallback if the `Guid` field is not set.
