Except it does. Using your logic, Luke Cage being able to completely no-sell a taser would have zero bearing on his ability to at least partially resist stronger electrical attacks.
If Hela can no-sell ship lasers, this tells us that her armour is at least somewhat resistant to Asgardian energy weapons. Which will provide at least some degree of protection against the Destroyer.
Also, the Destroyer's blast couldn't even kill one of the Warriors Three, at 1:28:
Not to mention it is kind of slow. Based on her fight against Asgard's army, Hela dances circles around it. And if Sif could pierce it, Hela will likely have no issues. And unlike Sif, Hela can use her blades as projectiles.
This is really not rocket science.
