Fix logout errors

[xsyann]

During the logout there is a short lapse of time where Meteor.user() is null, if the logout is performed on character or media settings screen the reactive template helpers are called and throw errors.

I think that rather than correcting these files it would be better to close all interfaces before launching the logout. What do you think?

Because I have the impression that we will encounter this problem again sooner or later 😕

Yes you're right, it's clearly a better idea and less error prone for the future to fix the cause rather than the consequences ^^
