Ability to test activejobs with relative delay

`assert_enqueued_with` and `assert_performed_with` were not able to
properly test jobs with relative delay. `:at` option was asserted for
equality and test will always fail cause small fraction of time will
pass between job call and assertion.

This commit fixes that by droping microseconds from `:at` argument
assertions.
