Hotfix: Balance display should not show the token and should not format the amount

[Tbaut]

closes #461
Only some very specific calls should have the balance displayed nicely with the token and the amount of decimals. Check the changes in constants.ts to see which ones. These will be nice in the manual extrinsics and in the call info, while all others should be in plank.

You can watch 7J9rSWpjfQjSYr1QDKPr6KjhnC2b2kLWfyBTiTpMgkNvD7vr on Hydra and see in prod how it shows HDX wrongly, and on this branch it doesn't.

Edit: Ok I added a some tests to check that

• the displayed value of an extrinsic not in the list is in plank
• the input value for the same, is also in plank
• the input value for an extrinsic in this list is in the denominated token.
• the display value, for an extrinsic in the list, is in HDX (from call data since it's using the same component as the transaction list)
