Custom field without label, inputName or model results in error

[will-fgmnt]

Failing to not specify any of these on a custom fields results in the following error:

vue.esm.js?65d7:1452 TypeError: Cannot read property 'toString' of undefined
    at e.exports.slugifyFormID (eval at <anonymous> (app.js:806), <anonymous>:7:12306)
    at VueComponent.getFieldID (eval at <anonymous> (app.js:806), <anonymous>:7:5340)
    ...

The documentation could be made a little clearer to specify at lease one of these values is required. Our particular use-case was we have a custom submit button which doesn't have a label or model.

Haven't got time to properly test this now, but probably changing src/utils/schema.js:65 from this:

return prefix + (schema.inputName || schema.label || schema.model)

to this:

return prefix + (schema.inputName || schema.label || schema.model || '')

would fix this.

Is it solved the problem? If yes, @dflock could you fix it in the repo?
