[MERGE] mail,web,*: JS mail and services tracebacks

* account,bus, web_editor, website, website_slides, web_tour

This merge fixes most issues where the webclient crashed with
discuss installed in mobile.

These issues occur due to the fact that the chat_manager, now
a service, was loaded after the webclient is instantiated.
The main idea of the fix is to let the webclient register services
that are loaded after its instantiation.

Despite appearances, the desktop mode had also this issue, but
most of the bugs were hidden thanks to the availability of tours
that are loaded after the module mail.
