[PATCH 1/2] test: known broken test for reindex tag preservation

[David Bremner]

In id:1588595993-ner-8.651 at TPL520 Franz Fellner reported that tags
starting with 'attachment' are removed by 'notmuch reindex'. This is
probably related to the use of STRNCMP_LITERAL in
_notmuch_message_remove_indexed_terms.
