test: add known broken test for duplicate thread-id terms

Browse source 
According to my bijection, this bug has been present since commit
411675a6ce in 2017. It is not completely clear what harm it causes in
regulary use, but it (at least) makes notmuch crash when compiled with
-DDEBUG_DATABASE_SANITY.
