Code model creates multiple file entries for differently cased files on case insensitive file system

Under some circumstances when using rename symbol under cursor then the symbol may end up being renamed incorrectly. With the attached example, if you go to rename the VectorNamesConfig_C symbol in the header file then the results show that the header file is referred to twice in the output. If both of these entries are checked then it will end up looking like:

class SourceConfig_Cblic QList<TestData::VectorGroupConfigItem_TP>
{
public:
    SourceConfig_C   SourceConfig_Ct QString& path_to_xml_file);
    virtual ~SourceConfig_Cublic:

If the second entry is unchecked then it works correctly.
