Add getEffectFromUuid_l to EffectChain

Add a function called getEffectFromUuid_l to ask if a specific effect is
available in an effect chain. There is already a similar function that
does the same but for a type, and actually only get the first effect
with that type even if there are several. It is more exact to ask for a
specific UUID.
