[FIX] web: fix quick edit tests

Before this commit, quick edit tests could crash in an undetermined way.
It was due to the setTimeout for the quick edit event in FormController
which waits at least 1 tick even if timeout = 0 like in those tests.
Now, if this timeout is 0 then we bypass the setTimeout.
