[bug] Can't cancel swap once an item has been hovered over

[yjukaku]

Describe the bug

When using the Swap plugin, it's impossible to cancel a swap once the swap threshold has been met for an item. You can't drag the item back to its original place to prevent a swap. This happens with or without the revertOnSpill: true option.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sortablejs.github.io/Sortable/#swap
2. Drag "Item 1" to hover over "Item 2", triggering Item 2 to get highlighted. Don't drop "Item 1", but instead try to prevent a swap by moving Item 1 back to its original place.
3. See: It's not possible to prevent a swap.

Expected behavior

Dragging Item 1 back to its original place, or off of the list, should deactivate the swap.

Information

Sortable.version == 1.10.2

I didn't include a code sandbox since it's visible with Sortable.js's own Github site.

Thank you so much for your work on this library!

I agree that your description is how it intuitively should work.

I've made a fix here: JoakimFFCG@90c4f89#diff-b4ffb7cc6e458fc5b1fca6d2ee32068db651d86a4b1bf5df9e411bcb10d2be40

Here is a demo: https://jsbin.com/zefoloboyi/edit?html,js,output

There have been a lot of changes in the master branch since 1.10.2 and when I compiled the source in the master branch myself, the swap plugin appeared to be broken (as in, the swap option didn't alter the behaviour at all; items were sorted normally).
So because I didn't have time to fix that as well, I based this fix on the 1.10.2 release tag. But, because there isn't any 1.10.X branch to merge this to, that means I can't make a PR, @waynevanson

Problem details
The cause of this problem was that all logic that determines what other element to swap with were inside the dragOverValid event function. However, that event is only fired when hovering over another swappable element.
I solved it by moving some logic to the dragOver event instead.
