Why this change?
This is a follow up to cc917a1d7f. It has
been identified that there is a circular dependency issue in our Ember
app with the user topic list route and it looks something like this:
1. `controllers/user-topics-list` imports `routes/build-private-messages-route`
2. `routes/build-private-messages-route` imports
`routes/user-topic-list`
3. `routes/user-topic-list` imports `controllers/user-topics-list`
This caused some weird problems in production where stuff would just not
load.
What does this change do?
1. Move `QUERY_PARAMS` from `controllers/user-topics-list` to
`routes/user-topic-list` which is the more apprioriate place for the
query params to be declared since they are route query params
after all.
