Bug description

1. Create a group for 1 person, that is yourself.
2. Video call in that group.
3. Only you are there in VC and the call is still going.
4. This doesn't make sense and should be prevented as this wastes resources.

Possible solutions:

1. Remove the Video call button.
2. Show a dialog/Toast when Clicking on the Video call button saying that VC with 1 person isn't possible.

I am ready with 1st solution PR, assign this issue to me to proceed.

This issue is fixed, but has a co-related issue. i.e. the Video call can be also started from ConversationSettings Screen. I have also found the responsible code for this and fixed it too.

However, I strongly believe this should be handled in a separate issue/PR as these changes are in a Separate File or Workflow. This will lead to better maintainability of the code and we can revert the PR if anything doesn't work as expected. Let me know if I should Open a dedicated Issue or Just a PR for this.

Note: The same situation applies to the Call History too. If all members in a group has left, then we should not allow making a call in the group. A separate PR needs to handle it(I am ready.)
