[FIX] mail: only prevent odoobot new messages during onboarding

Before this commit, new messages from odoobot were never opening
a chat window automatically.

This is desirable only during the onboarding process of the user,
when first logging-in, as to not bully the new user. It is not
intended to prevent all new messages from odoobot.

This commit fixes the issue by only preventing auto-opening of
chat window of odoobot for the 1st step of the onboarding process.
