Show connecting hearing devices in A11y hearing devices page

Browse Source 
We only show connected hearing devices in the hearing devices page now.
When user pairing a device from pairing page and back to the hearing
devices page after the device is bonded, it's confusing no device shown
in the list because the device is still connecting to profiles. We
should show the connecting device to avoid confusion.
