TRACKLIST_TOOLS: “Set selected works’ recording dates” broken

[ProfChris]

I have noticed that the set recordings date feature of this script has stopped working. Any chance of getting it repaired, as I find it a very useful feature

This menu item does not work any more, indeed:

Set selected works’ recording dates ← TRACKLIST_TOOLS™

[jesus2099]

I should see how #70 was fixed.

[jesus2099]

It does not work at all but anyway I should not use checkedWorks as it’s a recording to work relationship that must be dated, not all occurences of that work.

[jesus2099]

So now I build my own list of checkedRelationships (recording to work) to narrow down the list given by MBS’ checkedWorks.
I could also narrow down even more by checking dates and everything, but it would be quite tedious for very unlikely to happen without it being an actual prior mistake in relationships.
