Add force_update to tasmota sensors (#47052)

* Add force update also to non-binary sensors as e.g. POWER Measurement agerage cannot be calculated otherwise. This is the same behavior as set with the obsolete tasmota detection

* add tests in binary_sensor and test_sensor for force_update flag

* satisfy flake8

* next try for force_update test but this time on the entity object which is the correct level

* once again satisfy flake8

* one more try for a test

* fix typo

* satisfy black
