The meaning of "make a point to" in this sort of context means "I will ensure that it happens."
Your original sentence should be either "I will make a point" or "I made a point" depending on whether Saturday's party is in the future or was in the past.
The other two don't work because you can't ensure the other person comes to your party. "I will make a point to call you to remind you to come to my party" would work, but you can't make a point to have someone else do something.
