Error on quoted identifier

[knutwannheden]

    @Test
    void quotedIdentifier() {
        rewriteRun(
          kotlin(
            """
              val c = `Any`::class
              """
          )
        );
    }

results in:

I looked into this, and the error is caused by an issue in visitResolvedQualifier. The FirResolvedQualifier#packageFqName is returned as kotlin for Any, which causes a parsing error.

This should be fixed without changes in the PSI based parser.

Fixed in PSI parser
