Title: Changed the visibility of helper methods in the FileLocator

These 2 methods are only used by locate() in the same file, so they don't need to be public.
Thus, making a direct call to one of them would break the resolution logic after a theme change as they always use the cached theme name. The update of the theme based on the ActiveTheme is done by ``locate`` only.
