Grant email to funders should also include the admin

### User Story

Every time a grant admin uses the email to funders feature it should also send an email to himself.

### Why Is this Needed

Every time I used the email to funders feature I was not sure if I posted a normal update or if an email was also sent. I actualy dmed people in Twitter to see if it worked.

A great way to alleviate such concerns would be to also email the sender/grant admin.
