Remove traffic circle names from the roundabout and rotary instructions

[mcwhittemore]

This is superfluous information most of the time as roundabouts and rotaries are visually obvious things. We should simply sat at the traffic circle, take the 1st exit rather than At {name}, take the 1st exit`

What's the use-case for not passing through information from the backend here?

At least in Germany there are lots of rotaries you really want to announce by their names e.g.

• Grosser Stern
• Theodor-Heuss Platz

whic are well-known and even tram and underground stations there are called by the rotary's name.

I would also like to add, that the places not necessarily are visually obvious: Two examples here. One of which is currently tagged with junction=roundabout, the other isn't. It isn't necessarily highly obvious, that this is a traffic circle. Names, as @daniel-j-h already mentioned can be far more obvious, based on train stations and similar.

So, talking this over with @MoKob a bit offline, I think I can force the step to use roundabout.exit.default when using OSRM Text Instructions to make mp3s.

This has been done for english, if other languages want to follow suite, they can via transifex.
