Ensure callback is called when invoking errorHanlder #347

A property, errorHanlder, was recently added which will be called
instead of throwing an error in the .flush() method. This is important
because errors in .flush() could, previously, only be handled via
process.on('uncaughtException', err => { ... }).
However, this property is currently unusable as, when the flush method
invokes this property, it fails to call the callbacks of the events
being flushed.
This commit makes sure the callbacks are called.

I'm not sure if it's important that I open an issue before a PR. If it is, I'm happy to retroactively open an issue. |

There was a problem hiding this comment.
Did this TDD style. If you comment out the done(err) in index.js, this test will fail.

We use this library, however, it started causing problems for us when
throw errwas added to the.flush()method. This has been documented here. (#320) For us it was resulting in process crashes when we receive an error message (like a 429) when emitting an event. We had to pin the version of this library to a version before this behavior was added.I saw, that the
errorHandlerproperty was added (#342) and was attempting to update our code to use it, however, when writing a test case, I saw that my event callback was never invoked whenerrorHandlerwas present and calledThis is because, in the
.flush(), everywhere else the method can end, we calldone(err), however we do not when looking for and invoking theerrorHandler. To reiterate the importance, it's a core bit of functionality of this library that the callbacks for events are invoked when the messages are flushed, so it's needs to occur in this instance as well.
