Bug with default parameters in embedded app (test)

[alexbyk]

#!/usr/bin/env perl
use Mojo::Base -strict;
use Test::More 'no_plan';
use Mojolicious;
use Test::Mojo;

sub e_app {

  # Embedded app
  my $eapp = Mojolicious->new();
  my $r    = $eapp->routes;

  # !Stash
  $r->route('/foo')->route('')->to(fe => 'beee');

  $r->route('/foo/welcome')->to(
    cb => sub {
      my $self = shift;

      # stash must be empty, because '/foo' isn't our parent
      my $fe = $self->stash('fe') || '';
      $self->render_text("hello$fe");
    }
  );
  return $eapp;
}

sub p_app {

  # Parent app with embedded on /emb
  my $app = Mojolicious->new();
  $app->routes->route('/emb')->detour(e_app());
  return $app;
}

my $EXPECT = 'hello';

# /foo/welcome route in e_app, p_app is our proxy. BAD!!!
Test::Mojo->new()->app(p_app)->get_ok("/emb/foo/welcome")
  ->content_is($EXPECT);

# /foo/welcome route in e_app directly. GOOD
Test::Mojo->new()->app(e_app)->get_ok("/foo/welcome")->content_is($EXPECT);

The main problem is when we have

$r->route('/')->to(cb => sub { ... }); 

All other routers became broken

Thanks for the clean test case, made it very easy to fix the bug. :)
