    fix: themes_theme_change_notify: error parsing theme.css on Windows.
    
    When loading a theme on Windows we always get an error like:
    themes_theme_change_notify: error parsing [path including drive letter to:]\theme.css: 
theme.css:8:99Failed to import: Operation not supported
    
    The location points to the end of the filename of the first @ import url string.
    This is caused by the string not being an url.
    Based on suggestions from Jehan and lillolollo we replace g_file_get_path
    with g_file_get_uri since an url is what is expected here.
    Since that function already escapes the string we also remove
    g_str_escape here.
