- Adds a test that schedules a post 5 seconds in the future and waits
for it to be published
- Reduced the time restrictions for scheduling:
- The minimum time in the frontend is now 5 seconds in the future (came
from 5 minutes in the future)
- The time picker now suggests 10 minutes in the future instead of the
minimum scheduling time (came from 5 minutes)
- In the backend, a post will be allowed to be scheduled if it is at
least 2 minutes in the past (came from 2 minutes in the future)
- The scheduler will publish a post if it is at least 5 minutes in the
past, and maximum 5 minutes in the future (came from 2 minutes)
