Make the method dequeue stop the current animation

There was a bug in the dequeue method of the FX module. It was not stopping
the current animation as it was supposed too. This bug is now fixed. Also,
I rewritten the test that @fuzzyma left commented. I changed its
implementation to not use the once callback since there seem to be some issues
when combining once and dequeue. The method stop was also modified, it now
call start only when it's revelant.
