Fixes a problem not showing remote video menu in case of all moderators. (#2130)

Removes hasRemoteVideoMenu from RemoteVideo.
In some cases where mod_muc_allowners is enabled we do not see the remote video menu. The problem was in the order of initialization of remote video component.
RemoteVideo#constructor -> Remotevideo#addaddRemoteVideoContainer -> Remotevideo#addRemoteVideoMenu  -> RemoteVideo#hasRemoteVideoMenu = true
Then in VideoLayout#showModeratorIndicator -> !remoteVideo.hasRemoteVideoMenu -> remoteVideo.addRemoteVideoMenu().
