Async testing v0.50.0a25

Backend library improvements, should improve automatic and manual adding of devices.

Async testing v0.50.0a24

Service device-remove is now fully working, including removal from the Integration.

Async testing v0.50.a23

Added:

• Automatic adding of available devices should be working. The device to add must not be linked to a Stick, it needs to be reset.
  This function is default enabled, can be disabled by Integration --> 3 vertical points --> System options --> Turn off the enable newly added entities toggle
• device-remove service is working, removal of removed device from HA integration-view - not yet working (sensors etc. will show as
  unavailable)
• device-add service is partly working. There will be an error after 15 secs and the added device will not show up.
  After a reload the added device should be shown.
