[PATCH 1/2] test: Add tests for write access to database from hooks.

[David Bremner <david@tethera.net>]

Recent changes to configuration handling meant the pre-new hook was
run while the database was open read only, limiting what could be done
in the hook. Add some known broken tests for this problem, as well as
a regression test for write access from the post-new hook.
