iOS can't access any online content after disconnected from realm due to device sleeping.

Summary:

Playing in a realm, if the device sleeps, you leave the realm, but then the realm never reloads in the worlds list.

Steps to Reproduce:
1. Enter a realm as a guest or owner

2. Wait for your IOS device to sleep

3. Reactivate your device

4. Open Minecraft

Observed Results:

You are logged out of your Realm, and the Realm list never reloads (infinite 'fetching realms' loading animation, as seen in Screenshot)

Current workarounds:

• force quit Minecraft after sleep and reopen
• Prevent the device sleeping using Guided Access mode (not good from a battery perspective)

Expected Results:

Ideally, sleeping the device doesn't log you out of the Realm, but if it does, the Realm list should load again quickly and let you log back in.
