Element Call | Room/Call Header is not doing as per design

### Your use case

#### What would you like to do?

As per figma, when there is an active call widget on screen, the top bar call buttons should be disabled

But currently the camera icon become a `Minize Call` that put the call in PIP when you **stay on the same room the call is in** or a `Maximize Call` to put back the widget from PIP to main panel

It is only doing that when you are in the room that call belongs to. Else it behave as expected

It is probable a good feature, as it allows to have the current chat in big instead of only in the right panel (it is the only way to do that.

But the icon is wrong in that case, should not be a camera icon
