Fix internal compiler error on importing invisible fake reference

Note that this is not relevant for LOCAL/INHERITED visibilities:
  - for LOCAL visibility it's impossible to have a qualifier
  - INHERITED is an intermediate visibility, we enhance it later
    (see resolveUnknownVisibilityForMember)
