[PATCH BlueZ 2/3 v3] unit: Add gdbus/client_string_changed

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

---
v2: Emit property change on idle to better emulate the async nature and add a
timeout so the test doesn't hang forever.
v3: Fail if timeout is reached
