[PATCH v2] bindings/python-cffi: search for config by default

[David Bremner <david@tethera.net>]

The previous (pre-0.34.2) constructor searched for a config file but
only if the database path was not specified, and only to retrieve
database.path. Neither of the available options (CONFIG.SEARCH or
CONFIG.NONE) matches this semantics exactly, but CONFIG.SEARCH causes
less breakage for people who relied on the old behaviour to set their
database.path [1]. Since it also seems like the friendlier option in
the long run, this commit switches to CONFIG.SEARCH as default.

This requires a certain amount of updating the pytest tests, but most
users will actually have a config file, unlike the test environment.
