Restore advertising enable parameters onResume

When starting extended advertsing, we're not saving the enabled set
duration and max events parameters together with set id. This caused
issue that we're reenableing advertising set with wrong parameters
when advertsinig_manager onResume().

We need to save the parameters as well at enabling advertising. Added
unit test to cover this change and validated the original issue exists
and the fix works.
