Service worker added some flakiness, we
activate the sw only if not from the CI.
We add as well the email of the user added in a
doc to the toast message. This way we can check
if the user was added correctly, this will remove
some flakiness in some tests.
Add or invite a user to a doc.
If the user is already in the system,
the user will be added to the doc,
otherwise, the user will be invited to the doc.
