Web3.js: myContract.events.MyEvent is broken in beta.49-51

[sydneyitguy]

Description

I think this issue is related to https://github.com/ethereum/web3.js/issues/2563 but the fix #2574 didn't apply on contract.events methods.

This issue has appeared on beta.49, and still existing on beta.51

Expected behavior

contract.events.Transfer({ fromBlock: fromBlock }, function(error, event) {
  console.log(event);
});

should log events.

Actual behavior

Error log
```
