Weaver tries to send e-mail to hashed notification_email

[perronld]

Describe the bug

In function submit_job_handler of weaver/processes/execution.py, Weaver hashes the value of notification_email and lose track of the original value, which makes notification impossible to send since it tries to send it to the hashed e-mail address.

How to Reproduce

Supply the "notification_email" option to a job.

Expected behavior

E-mail should be sent to the address specified in notification_email
