Use call note text from highest priority source

[alduhoo]

The call note extension has support for updating the call note source priority. When fetching the note text to display, the text from the last source was being returned (this was expected before the priority re-ordering change). To simplify things and have the text match the expectations of the prioritized list, return the note text from the first source.

It might be a bit confusing, but priority is first note found within a file, but last file in the list.

This is because if you add a new file, you expect it to have priority. Otherwise the default Ham2K Notes file would always take precedence unless you reordered them.

One alternative would be to change the logic to what you propose here, but it would also require a migration to reorder files each user might have already added, and changing the way the UI works so that new files are added on top.
