Revert "Track WinRT device connection status"

This reverts commit 2f4e14b295bb503f51758a69a650dc1dda31b09a.

Reason for revert: Most likely culprit for the consistently failing Windows devices tests (also bluetooth-related).

Original change's description:
> Track WinRT device connection status
> Windows sometimes sends OnConnectionStatusChange events when the status
> has not changed. Previously we had assumed the status changed and acted
> accordingly.  This change keeps track of the connection status and if
> OnConnctionStatusChange fires with the same status it is now ignored.
