Email settings in ENV vars override those in dashboard

[mikemurray]

Expected behavior

If credentials from ENV vars will override the mail settings in the dashboard, then they should be displayed in the dashboard.

Actual Behavior

• Credentials from ENV override settings in dashboard, but the dashboard does not reflect that.

Steps to Reproduce the Behavior

• Export bad mail settings
• Reset and run reaction
• See errors in terminal when emails fail to send

export MAIL_URL="smtp://postmaster%40sandboxXXXX.mailgun.org:BAD_PASSWORD@smtp.mailgun.org:587"

And email form should probably be more consistent, keeping API Key and credentials [as an option or dully marked not all inputs are always necessary]. For example, send grid can use API key or user credentials.
