Implicit receivers generally do not affect the resolution of types.
However, they generate scopes which might contain undesirable
classifiers, which can confuse reference shortener.
Dropping all the implicit receivers when dealing with type references
allows completely avoid such undesirable scopes instead of filtering
them by `instanceof` checks.
Also, temporary move `hasTypeParameterFromParent` check higher to the
`findClassifierElementsToShorten`, because ATM we don't know how to
properly decide whether to shorten the fully-qualified inner types
with implicit parameters or not (see KTIJ-26072).
