KT-62675 [AA] Handle labeled this expressions in reference shortener

At the moment, there is no good way to meaningfully filter `this`
expressions. The filters for the reference shortener can work only with
symbols, and it does not make a lot of sense to check any particular
symbol when deciding whether to shorten a labeled `this` expression.

We would probably need a better API for the shortener to be able
to filter more precisely (see KT-63555)
