mail_base breaks all other modules which use bus notification

[alex2grad]

Need to remove
bus.off('notification');
from mail_base/static/lib/base.js

Calling .off() with no arguments removes all handlers attached to the bus

Just removing will break the mail_base module...

[alex2grad]

No, removing it breaks nothing. I checked.
Why do you think it breaks mail_base?

If you want to remove mail_base's event you should provide the selector and event arguments.

I mean that is was added by a purpose. As I remember, it's needed because we copy-pasted code from original mail module and without .off() we'd have duplicates fo the handler.
We can take a look, if you make a PR
