Release 2387
Trello card
Context
We want to be able to indicate to the user if there are going to be any results for a given search filter.
Changes proposed in this pull request
- Add total counts to school search filters
Add counts to each filter; if they are in the same group they are OR'ed together, whereas different groups of filters are AND'ed together.
Remove the brackets from the phase labels to avoid doubling up, e.g. "Primary (11 - 14) (2)".
- Fix broken Cucumber tests
Unrelated to my changes, but I noticed we had warnings from Cucumber that a few steps weren't defined; this defines them and/or fixes the underlying tests.
