KT-61568 [FIR][AA] Do not add redundant file scopes in AllCandidatesResolver

`firResolveSession.getTowerContextProvider` should already
contain all the relevant scopes, including default and
importing scopes for the file

Because of this, import and default scopes had presence over the
more local scopes, and the resolve was performed incorrecty - top level
candidates were given higher priority
