CodeModel: Renaming class does not rename occurrences inside macros

Steps to reproduce:

• open / create a Qt Unit test (or any auto test of QC's sources)
• make sure the test contains one of the macros QTEST_APPLESS_MAIN, QTEST_GUILESS_MAIN, QTEST_MAIN
• place the cursor at the class definition and invoke 'Rename Symbol Under Cursor'
  • give it a new name and hit <Return>

Current result:

• all occurrences are renamed, except the occurrence inside the macro

Expected result:

• the occurrence inside the macro is renamed as well
