Fixed #36796 -- Handled lazy routes correctly in RoutePattern.match().

Coerce lazy route values to `str` at match time to support prefix and
endpoint matching when using `gettext_lazy()` route paths.

Regression in f920937c8a63df6bea220e4386f59cdb45b2e355.

Thanks to Andrea Angelini for the report, and to Jake Howard and Jacob
Walls for reviews.
