Pardon removes that risk. A pardoned criminal is a criminal with no 5A.
Folks. Let's think this through.
Trump can only pardon while in office. But he can be CHARGED with crimes forever after.
So let's think from Trump's perspective. If he's charged in 2020, would he want Flynn, eg., to have 5A?

Uh. Nope. Refusing to testify is a new, separate contempt crime. And now, there's no one left to pardon them. Bc Trump's out of office.
HAHAHA. They'd do whatever they had to do, to stay out of jail. Since they'd been pardoned for the ORIGINAL crimes, they'd have zero incentive to do anything but tell the truth (and hang Trump) on the ORIGINAL crimes.
He's not going to pardon ANYONE. At least, not his co-conspirators. He might be able to get Pence to do it if he's impeached. But what does Pence gain?
But I view the correct answer as "yes."
