Title: Disable delivery methods even for preview action

I'm using letter_opener gem to inspect email locally at the time when they are sent. However, I noticed that using email_preview with letter_opening causes a problem - when I click to preview an email in EmailPreview admin, emails are generated and opened in the browser. This is a PR attempting to fix this situation.

Please let me know if you have any thoughts about this
Thanks
