Queries: Update API to align data with previous versions

Ensures fields returned match API docs and previous versions of
BookStack where we were accidentally returning more fields than
expected.
Updates tests to cover many of these.
Also updated clockwork to ignore image requests for less noisy
debugging.
Also updated chapter page query to not be loading all page data, via new
query in PageQueries.
