tests: Ensure session bus has started before integration test

The session dbus-daemon won't necessarily be run immediately on login
if we are using systemd socket activation for it, and the transient
services directory $XDG_RUNTIME_DIR/dbus-1/services isn't created until
it's actually run. Ping the dbus-daemon to make sure it's available.
