[Patch v2 4/9] test/tagging: add test for error messages of tag --batch

[david at tethera.net]

From: David Bremner <bremner at debian.org>

This is based on the similar test for notmuch restore, but the parser
in batch tagging mode is less tolerant of a few cases, in particular
those tested by illegal_tag.
