[PATCH v2] test: Add test for messages with missing headers

[Austin Clements <amdragon@MIT.EDU>]

Currently the JSON tests for search and show are broken because
notmuch attempts to dereference a NULL pointer.
---
This version fixes the "Show: text" test so that it sanitize its
output and doesn't hard-code my test paths.
