Seems like the simple fix - make the impact of Tenacity affect all types of self healing, whether it be spell, trait, ability based on damage done or lifestealing. No reason for it to be otherwise - although if Tenacity also buffs the outdoing damage, there is in effect a double dip, but the amount is small enough to be ignored.
