Panic when deploying after kick merge

[Brawdunoir]

#111 results in a panic in render during deployment.

panic: ':roomid' in new path '/rooms/:roomid/kick/:userid' conflicts with existing wildcard ':id' in existing prefix '/rooms/:id'

Apparently, we just need to rename :roomid to :id in route.

Basically, both routes need to have the wildcard in the same position, and the wildcards need to be named the same thing.
