[IMP] web_editor: show drag & drop tooltip helper faster

Before this commit, if the user mousedown a snippet, it would start a
timer of 1500 ms and a the end of the timer, it would show a tooltip to
help the user indicating him that he should drag & drop and not click.
The drag & drop code would (sort of) stop that timer if a drag was
detected, to not show the tooltip if the user is correctly drag &
dropping.

But it feels weird, as when you fail to realize you should drag & drop
but click instead, you only have the hint 1.5s later.
Some internal people would actually use triple click on snippet when
trying to show this tooltip, because it's probably not easy to figure
exactly what the trigger is.

The change is then made to show the tooltip directly on mouseup.
If the drag & drop code did not indicate that a drag happened, we can
safely assume it was a simple click and not a drag.
