Localized sites URI is not taken into account

[dbismut]

Description

Let's say there is a US site and a France site.

US site is available through your-domain.dev.
France site is available through fr.your-domain.dev.

US section for players URI is /players/{slug}, template is /players/_entry.
France section for players URI is /joueurs/{slug}, template is /players/_entry.

I would expect URL for a player entry to be:

• US: your-domain.dev/players/my-player-slug
• France: fr.your-domain.dev/joueurs/my-player-slug

However, Craft returns a HTTP 404 - Not Found error saying Template not found: joueurs/my-player-slug when accessing the France URL. However, fr.your-domain.dev/players/my-player-slug does work.
