Whenever a link is connected/deleted to a multi-input socket, it needs to be re-indexed.

It seems that this was a bug even in the python interface.
So this simplification should be effective.
And also, I do not think that this will create problems in speed.

It seems very easy to introduce O(n^2) complexity. Not sure I have a better solution, but maybe this needs to be at a higher level to make that more obvious or something

We might check if cache is computed and use it. But not sure if this can be better.

Hmm, that might work.

Big picture, the only reason this multi input index isn't just runtime data or computed on the fly is the currently dragged link has to add to the indices.
