…tivated - EXO-76187.

Before this change, when deactivate Jitsi and external videoconference in the administration and check on any field which is group synchronized then click on the 3 dots of a user in the results, empty place where I'm should have the videoconference option. To resolve this problem, add a check condition if Jitsi is initialized in the  extension. After this change, if jitsi is disabled menu action is only display the available options without empty space.
