Transit layer's route_name should be simply name

The convention in Mapzen vector tiles is to have name regardless of source OSM feature type. But I see route_name on all transit line features.

(In this case we also indicate that "osm_relation": true, on these features already.)

Example 1:

{
"colour":
"#008752",
"id":
-3433314,
"kind":
"light_rail",
"operator":
"San Francisco Municipal Railway",
"osm_relation":
true,
"ref":
"M",
"route_name":
"M-Ocean View: Outbound to Balboa Park",
"sort_key":
418
},
"type":
"LineString"

Example 2:

{
"colour":
"red",
"id":
-2851509,
"kind":
"subway",
"operator":
"BART",
"osm_relation":
true,
"ref":
"Red",
"route_name":
"Richmond-Daly City",
"sort_key":
275
},
"type":
"LineString"
},

We have a transform that removes route_name from the results if it's the same as name. Presumably there are cases where route_name is not the same value as name?

How about:

• if route_name exists but not name -> move to name
• if name exists and equals route_name -> drop route_name
• if both exist and are different -> keep both

We have this transform configured for the roads layer too.

Sounds good to me :)
