MDL-17647 was referring to moodle/site:candoanything insstead of moodle/site:doanything
MDL-17648 Let get_users_by_capability take an array of capabilities, like has_any_capability
MDL-17649 get_users_by_capability must have unit tests (HEAD only).
The unit tests were briefly working (apart from the system context, which I had to set up by hand in the test contexts table). Then I made the mistake of trying to upgrade the test tables, and it all went horribly wrong (MDL-17644).
