Guard extra call in ZHA lights (#47832)

* add flag to prevent sending an on command

* fix condition

* add constant for default transition

* make groups work with new force on flag

* reorder light entity creation

* rearrange logic

* update test

* remove failed attempt at group light flag

* fix flag
