Pagination doesn't work properly for pending incidents

Related to #8

First two pending incidents pages for /incidents (page 0 and page 1) return the exact same result.

Start at the API handler for /incidents and reproduce the two linked requests with status=Pending, page=0, and page=1. Trace how pagination is applied to pending incidents and verify that the two pages return different results; done means the reported duplication no longer occurs.
