Calculate total for crawl QA page endpoint (#2435)

Fixes #2434 

Patch fix for a regression in Browsertrix 1.4.0-1.4.1 where total was
not being calculated for QA page list endpoint but still being included
in response, which led to total always being 0 and pages not loading in
the frontend review screen as a result.
