Attempt to fix multiple recipient edge case within `SendEmailHandler`
Attempt to fix multiple recipient edge case within `SendEmailHandler`

Since the `send-email` is being generated more often, the error with
multiple recipients within send() method started to appear. This
could have happen due to sender not being reset before setting
email parameters.

Just to be sure, we're now resetting sender state before we start
configuring email parameters in the `SendEmailHandler`.
