[FIR] Fix incorrect updating of callable reference type in delegated property

... if the delegate happens to be a function call whose second
argument is a callable reference but not actually a provideDelegate
call.
The fix is to ensure that the call is _actually_ a desugared
provideDelegate call.

This fixes a CCE in a case where the delegate expression is a regular
function call and the second argument is a callable reference.
