PURPOSE
Be defensive when dealing with email fields, notably when having multi-emails
or email field containing an already-formatted email.
SPECIFICATIONS
When possible, use 'email_formatted' field on partner, instead of calling
'format_addr'. That way management of corner case input (multi emails and
double encapsulation) is managed by the computed field itself.
When 'format_addr' has to be used, ensure email part is normalized to avoid
formatting issues.
Also use tools to extract emails instead of 'email_re' regex when possible.
That way all code extracting and managing emails go through the same stack.
