State is undefined

[adammankowski1]

Expected behavior (user story)

Clicking the register button on the main page (Create new instance of MachineOwner contract) should create new instance of MachineOwner contract and give access to register new machine.

Actual behavior

After clicking the register button on the main page application throws App.js:132 Uncaught TypeError: Cannot read property 'state' of undefined
It is for sure related to App:144 where we put callback without binding it.
The same is with App.js:L148-L149

Steps to reproduce

1. Click the register button on the bottom of the page
2. Check console for undefined state error
