Prohibit instance access before super call

- Before this change members just left unresolved as they were absent in the
  specific scope named scopeForSecondaryConstructorHeaderResolution that
  created just to prohibit such accesses.
- Now they are resolved the same way as other members, but diagnostic is
  repored by in-place injected CallChecker
- Drop obsolete type of class scope
