[PATCH] test: add known broken test for duplicate thread-id terms

Subject: [PATCH] test: add known broken test for duplicate thread-id terms

According to my bijection, this bug has been present since commit
411675a6ce in 2017. It is apparently harmless for regular use, but
does make notmuch crash when compiled with -DDEBUG_DATABASE_SANITY.
