Subject: [PATCH] sessionMode: Drop allowExtensions property

Now that we allow extensions at the lock screens, extensions
are allowed for every session mode gnome-shell would typically
change to at runtime.

This means there's little advantage to having an allowExtensions
property in the session mode definition.

This commit simplifies the code a bit by dropping the property.

Third party session modes can still lock down extensions through
gsettings if they need to.
