Use display name of the crypto for filtering transactions instead of the internal name

[ikyslyi]

The filter drop-down contains internal crypto names in the list.
For better UX it should contain crypto display name, e.g. "Ethereum" instead "ETH".
To achieve that, api should return not the only Crypto.instances.keys(), but display name as well, and j2 template should use the proper one for the Name and for the Value in drop-down.

don't forget to check another places where that endpoint used and test if the changed model doe not brake anything

see this fix for reference of the initial bug description.
