If a potential receiver is resolved to an error type, we consider any other type as a subtype of it and therefore may select any candidate that we happen to find in a scope. In particular, in the case of scripts, or code with a context receiver, the receiver candidate resolved to a cycle was accepted as a receiver to an invoke on a random class from stdlib. The fix skips adding invoke resolve task in this case, allowing the tower to find the correct candidate in another scope. #KT-64241 fixed #KT-65576 fixed
