No feedback given when joining a closed portal

[jasonrudolph]

Steps to Reproduce

1. Host: In one Atom instance, share a portal and then close the portal. Leave Atom open.
2. Guest: In another Atom instance, attempt to join the portal created in Step 1.

Expected behavior: Guest should receive some feedback that the portal cannot be joined.

Actual behavior: Guest sees nothing.

Reproduces how often: 100%

Additional Information

If the host closes their Atom instance before the guest attempts to join the portal, the guest will see the following error when attempting to join the portal:

Failed to join portal
Attempting to join portal 6c2935e5-5cda-4f7c-a46b-dd4ca1c63d89 failed with error: Connecting to peer timed out

But, when the host still has their Atom instance open, we instead observe the bug described above.
