Sleeping on a Realm requires players to leave and reenter bed.

When multiple players attempt to sleep on a Realm, but one instead enters the Nether, it does not become day.

What I expected to happen was...:
Having one player in bed as one entered the Nether immediately skip to day.

What actually happened was...:
The sleeping player was required to exit and reenter the bed after to skip to day.

Steps to Reproduce:
1. Have two players on a Realm at night.
2. One gets in bed.
3. One enters a Nether portal.
4. Nothing happens.
5. First player exits and re-enters bed.
6. Skips to day.
