Leo McArdle 99527af38a FIX: show rejected emails with unrecognized errors (#5026)
Although 407a23663df6c8e66c5c3b8e5cbf21a609de4109 will send rejection
messages for unrecognized errors, sometimes processing the email will
raise an error which has a blank message.

This commit:

1. Shows rejected emails which have already been processed and contain
   a blank error in /admin/email/rejected

2. Replaces new blank error messages with the error type
