[FrameworkBundle] RedirectCotroller: The ignoreAttributes parameter should be ignored

As discussed in PR #7590, when pointing a route to FrameworkBundle's `RedirectController` the attribute `ignoreAttributes` is added to the new route's attributes, if specified as array. As @lsmith77 wrote in a comment to that PR, this should not be the intended behavior. A valid workaround is to add `ignoreAttributes` itself to this array.

The problem remained undiscovered by the unit test, as `ignoreAttribues` was not included in the `_route_params` of the faked `Request` object. This PR should fix both, the unit test and the `RedirectController` itself, so the workaround mentioned above is not necessary anymore. Additionally, my fix should not break any routing configuration that is using the workaround.

Print form name in form_start function

It'd be useful if form_start() prints the form's name.
This way if you want to test it in your page, you can catch the form by `$crawler->filter('form[name=my_form_name]')`
