Martin Gräßlin 2273fc0559 Cancel the EffectLoader query on clear
The Scripted and PluginEffectLoader perform locating all effects which
are to be loaded in a thread. When the EffectLoader gets cleared so far
the query did not get canceled. This resulted in effects maybe getting
loaded.

This problems shows on build.kde.org if the test is too fast and tears
down the Effect system while effects are still being queried.
