Routematch parameters with multiple values return space instead of +

Attached patch used to fix the issue

Thanks for reporting

So it's recommended to open MRs vs patches as DrupalCi is shutting down in replace of gitlab.

As a bug will also need a failing test to show the issue

Changing to 11.x as the current development branch. Bug fixes can be backported to supported branches when committed.

I am testing if the modification cause other issues as a side effect of the applied patch.

Now if you try to access a url like this:
/books/horror+thriller it redirects to /books/horror%2bthriller

I am checking why there is this redirect in place.. if anyone have suggestions it would be appreciated!
