lib: move deallocation of memory from n_d_close to n_d_destroy

In order to mimic the "best effort" API of Xapian to provide
information from a closed database when possible, do not
destroy the Xapian database object too early.

Because the pointer to a Xapian database is no longer nulled on close,
introduce a flag to track whether the notmuch database is open or not.
