[Bristol] Remove category search for Bristol

As Bristol are using extra questions for some categories
(types of pothole) the filter doesn't pick these up
and presents the only available category of pothole
which is in a park.

Will be resolved by Bristol making changes to their
categories which they will do in the future.

In the meantime, we remove the category for them.
