Same as generateCacheName, but returns complete path to cache.

If no filename is given, you need to add the file extension by yourself!

@param string $filename     The filename of the file that should be cached. If empty, a unique filename will be generated.
@param string $prefix       Adds a prefix to the generated name. Only if $filename is empty.
@param bool   $more_entropy A longer name for the unique filename. Only if filename is empty. Default

@return string the path including the filename to save the file to the cache
Same as generateCacheName but returns complete path to cache .
