Forces the configuration file to be loaded, even if it already was;
 this first resets the configuration using {Brandish.reset_configuration},
 then it loads the {#config_file_path}.  If no configuration was provided,
 it fails;  if it didn't load properly, it fails.

 @raise [RuntimeError] If no configuration was provided, or if it didn't
   load properly.
 @return [Configure]
