[PATCH BlueZ 2/9] Return at least the title attribute from player_list_metadata()

[Emil Velikov via B4 Relay <devnull+emil.l.velikov.gmail.com@xxxxxxxxxx>]

From: Sam Lantinga <slouken@xxxxxxxxxx>

This fixes Bluetooth AVRCP certification test AVRCP/TG/MDI/BV-04-C,
which requires a valid response from the get_element_attributes command.
