Fetch current active and selected programs at Home Connect (#136948)

* Fetch current active and selected programs

* Intialize HomeConnectEntity first at SelectProgramEntity

* Use the right exception

* Use active/selected program from `get_all_programs`

This will allow us to reduce the number of requests that we need to perform to get all the data ready (only one requests vs. three requests)

* Remove no longer required mocks

* Fix
