Use "Rückgängig" instead of "Zurücksetzen" for Undo

@langhard: Yes, Zurücksetzen is quite confusing, Rückgängig is much better for undo.
Currently I have to override the ra.action.undo translation, please merge!

import germanMessages from 'ra-language-german';
import merge from 'lodash.merge';

// Fix german message
// (@see https://github.com/greenbananaCH/ra-language-german/pull/20)
const germanMessagesFixes = {
    ra: {
        action: {
            undo: 'Rückgängig',
        },
    },
};
const germanMessagesFixed = merge(germanMessages, germanMessagesFixes);

export const messages = {

    ...germanMessagesFixed ,

    // ...

}
