Initialize translation set after reading user config

This allows having per-repo config files with different languages per repo. Now
granted, this is not an important use case that we need to support; however, the
goal is to eventually make all configs hot-reloadable (as opposed to loading
them only once at startup), so this is one step in that direction.
