Editing Notes Creates New Notes Stacked On Top Of Each Other

[BrokenEagle]

Shounen_Fake noticed this issue on post #2527315, a post that I had translated. It had triple stacked notes in the same location. I thought it must've been an error that I made, but then I came upon post #2528809 with the same issue. This one had quadruple stacked notes. I've already deleted the extras, but you can still see them in it's history.

I did remember when translating post #2527315 that after I had hit the Save button, the outline of the text box remained red instead of going black. So I then retested this on testbooru, first creating a note, then opening it up for editing without reloading and modifying it before resaving it again. The end effect is that it ended up creating 2 notes in the same location stacked on top of each other. You can see this demonstrated at the following link.

I think PR #2748 fixes this, but I don't use notes so I'm not positive. I have it running on http://devbooru.evazion.ml:3000/, can you test it?

Tested it on http://devbooru.evazion.ml:3000/posts/1 and it works as it should.
