Creating a direct message channel, inviting a user, then turning on end to end encryption results in failure to exchange keys

[michaeljgray]

Description

Enabling end to end encryption after inviting a user to a direct chat channel presents the invited user with an error saying that the initiator of the invite needs to verify keys, even though keys are already verified.

Steps to reproduce

• User A and User B enable "Do not send to unverified devices" on their client settings
• User A verifies keys with User B
• User A creates a direct chat with User B
• Before User B accepts the invitation, user A enables end to end encryption
• User B accepts the invitation
• User B is presented with a key validation error
• User B can try to initiate verification, but User A never sees it
• User A does not see any errors
