• Moved and updated/Added tests

[j4m1ef0rd]

As discussed, I will be refactoring this to move the params (including the Fok param) to the swapping pallet so that we do not have separate limits for each chain that need to be updated separately. I will also be changing the 2 DCA parmas to be 1 param: maximum total swap request duration blocks

Some weirdness with the dca merge. Will rebase and fix.
