Edit button showing when not connected

[Heraes-git]

This topic is not a dupplicate but might be connected to #16.

Right after installing and setting properly the FrontendEditButton plugin (with requiresAuth: true), the FEB button stayed visible while I was logued out.

I logued in to the admin by accessing the URL and/or clicking on the FEB button, and logued out ; but the FEB button was still visible.

That's only when I used the in-page form of the login plugin that I implemented in my template, to log in and log out from that same form, that the FEB button seemed to receive the deconnexion and disappeared.

So it implies that some users on my website could see the button the first time they come, and I wonder if some unregistered users could see it.

edit :

It also seems that after loguing out, while the FEB button seems to disappear, it comes back if I route to an other page.
