Fix openzeppelin-solidity/contracts/ownership/Ownable.sol

[harshitsinghai77]

In the latest version of openzeppelin, this has been moved.

Install
npm install @openzeppelin/contracts --save

Instead of

import "openzeppelin-solidity/contracts/ownership/Ownable.sol";

use it like this

import "@openzeppelin/contracts/access/Ownable.sol";

Thanks @harshitsinghai77 I'll set up some time soon to make this change along with a handful of other errata.
