De-flake BluetoothLowEnergyWeave* tests.

De-flake BluetoothLowEnergyWeave* tests.

The issue was that ProximityAuthBluetoothLowEnergyWeaveClientConnectionTest set up "test" factories but did not un-set them once the test was over. The result is that two other tests used these test factories in their tests, which caused failed assertions.
