Tests: Increase robustness of a draggable `revert` test

One of the changes is increasing `revertDuration` from 200 to 300. For some
reason, when jQuery 3.1 is used in an iframe (which TestSwarm uses) the timings
are lower than expected and `setTimeout` too slow and the check for animation
happens too late.

Closes gh-2230
