Resolve issue in custom-cards#3 where the functional step count was a…

… result of both

the step and the max of an input_number entity.

Appears that at this time applyStep() is unnecessary, and was in fact
causing the problem  I have tested stepped sliders of both input_number entities as well as
light and climate entities, and stepping still works as expected when
applyStep() is not called at all.

This does not resolve the issue where step count results in "illegal"
values on certain input_number entities.
