have_enqueued_sidekiq_job fails frequently because of nanoseconds

[lastobelus]

This generally happens when a time calculation has gone through a db round trip.

My current workaround is to use Timecop to freeze now without nanoseconds at the beginning of each spec:

          now = Timecop.freeze(Time.zone.now.change(nsec: 0))

but I think it would be better if have_enqueued_sidekiq_job dropped nanoseconds from both sides.

I believe this was fixed with https://github.com/wspurgin/rspec-sidekiq/commit/dcc6d037a2333a5af73ead81809b484fd0e9ac13 which drops any fractional second component. However, It's always a good idea to freeze time for any time-based expectations to avoid flaky failures.
