web3.eth.Contract.getPastEvents doesn't support "allEvents" anymore

[mistersandman]

Expected behavior

Using "allEvents" as event name in web3.eth.Contract.getPastEvents should be accepted and return all events matching the specified options according to the docs.

Actual behavior

An exception "Error: Event with name "allEvents" does not exists." is thrown.

Steps to reproduce the behavior

Call getPastEvents on a contract with the first argument (event name) set to "allEvents".
