^ KTIJ-24373
when resolving selector expr of a dot qualified expression,
parent qualified expression is resolved
see `KtFirCallResolver.getContainingDotQualifiedExpressionForSelectorExpression`,
Fir is filled with the data. Then,
during final mapping from Fir -> psi, one need to perform the opposite:
take `selectionExpression` to get the initial KtCallExpression
- `toResolvedCallableSymbol`: cast defensively because
the resolved symbol might not be a callable symbol.
- `toKtCallInfo`: Check that the resolved symbol is actually callable.
