Check extension receiver properly for property references

Without this, the unrelated type specified on the LHS of a property reference
literal was considered to be an extension receiver of the candidate, and the
resolution was erroneously successul. This is only reproducible for properties,
because if we're trying to resolve an extension, we consider all properties
from the scope, even non-extensions, because there may be a property of an
extension-functional type (T.() -> R). (We don't do this for functions.)
