Ensure that any bluetooth scan started (by changing the device name) in the
download-from-dive-computer dialog (desktop version) is stopped before the
download process is started up. Because the QT bluetooth discovery agent uses
a QTimer internally, it must be stopped from the same thread as it was started
from. The download process uses a different thread, so ends up crashing when
it tries to dispose of the timer from a different thread.
