UI shows gray padlock for encrypted room before joining it

[AndrewFerr]

Steps to reproduce

1. Join a knock-restricted room for an encrypted call
2. Send a knock
3. See a gray, slashed padlock near the top of the screen, suggesting the call is unencrypted
4. Wait to be allowed into the room
5. See that the gray padlock is now green

Outcome

What did you expect?

The padlock should be green from the beginning, or if there is insufficient information for ECall to know whether the call is encrypted, there should be either no padlock or a new icon to indicate an indeterminate encryption status.

What happened instead?

The padlock was gray until being granted access to the room, at which point it turned green.
