Add reset for redirect loop check in redbean Route

Browse source 
Without this reset a combination of RoutePath() and Route() calls
could return "508 loop detected", since RoutePath could be called
twice for the same redirected path.

The protection against looping is still there, as it can only
loop inside the Route() call (as it always serves something).
