* validate.message was used in tandem with validate.test
* it might be confused as the message if the validation for validate.type failed
* now validate.test can be a function or an object of { test, message } shape which matches Yup.test
* I removed wallet.server in a previous commit
* the client couldn't determine which wallet was stored on the server since all server specific fields were set in server.js
* walletType and walletField are now set in index.js
* walletType is now used to determine if a wallet is stored on the server
* also included some formatting changes
* wallets now consist of an index.js, a client.js and a server.js file
* client.js is imported on the client and contains the client portion
* server.js is imported on the server and contains the server porition
* both reexport index.js so everything in index.js can be shared by client and server
* every wallet contains a client.js file since they are all imported on the client to show the cards
* client.js of every wallet is reexported as an array in wallets/client.js
* server.js of every wallet is reexported as an array in wallets/server.js
FIXME: for some reason, worker does not properly import the default export of wallets/server.js
* remove resolverName property from wallet defs
* move function into lib/wallet
* use function in generateMutation on client to fix wrongly generated mutation
