Implemented a bunch more selenium tests for "manage users" view. Also updates http-mock module to allow assertion of requests made to backend.
Manage users controller now discards user edits correctly when abort is clicked during edit-mode.
Updated manage users tests to reflect the changes in previous commit
Manage users will no longer bug out when aborting delete and in general chaining multiple deletes in one session.
Last mange users test no longer bugs out because of bootstrap dialog fade out animation
