[IMP] hr_contract: disable email when a contract is about to end

When a contract is about to end, an activity is scheduled for the hr
responsible to act on it. Also, from task 2759601, a new warning was created
showing the contracts that are about to end. Therefore, sending an email to
the hr responsible started being too intrusive. This commit drops the email
sending for this case.
