Revert "Index records with a canonical name"

This reverts commit 5b27322f8e763de855d1dc78dc3292f03ff7633e.

I need to look into this more. The spec doesn't pass, and I don't
immediately understand the problem or the fix.
Test multipart emails, remove URI parsing to path

As noted in the comment for this PR
https://github.com/ianwhite/pickle/pull/17 this strips out URL
params, and it also only tries to open the path where as I think we
should stick with the original intent of opening the exact link from the
email. Your environments/development.rb (or test) should set the proper
base url so that links in emails will go to the test url properly.
