Disable all Track detach buttons when one is clicked

closes #2528

why are we disabling all the Detach buttons and not only the one which is detached?

[hackartisan]

@christinach the whole page reloads when you click a button. it's not really intended to support multiple detach actions at once.

I understand. Thank you @HackMasterA . Maybe this is something that we can improve. -> not loading the whole page when detaching.

[hackartisan]

@christinach for example, I just tried it with just disabling the one I click. I was able to click 3 buttons before the page reloaded, and see them all spin, but then when the reload came through, 2 of those had been removed and the 3rd was still there.

Yes it would be nicer if it didn't reload on these actions. this was a quick/dirty implementation.
