Use env['action_dispatch.routes'] to determine if we should generate …
…prefix or not. This technique is here to allow using routes from Engine in Application and vice versa. When using Engine routes inside Application it should generate prefix based on mount point. When using Engine routes inside Engine it should use env['SCRIPT_NAME']. In any other case it should generate prefix as env should not be even available.
