Would be nice to see which were the params sent when they were not received

Today I spent a considerable amount of time debugging why my job wasn't being scheduled, I was seeing an output like this

Failure/Error: MyWorker.should have_queued('first-param', 'second-param', 'third-param')
       expected that MailDeliverer would have [first-param, second-param, third-param] queued

I wasn't finding the origin of the problem, until I realised I had a typo in the params I was sending when enqueuing the job, something like this (notice the type on 'third param'):

Resque.enqueue(MyWorker, 'first-param', 'second-param', 'third param')

So what I'm proposing is to modify the matchers to make them give more details when fail, so that they say what was expected and what is being received, something like this:

Failure/Error: MyWorker.should have_queued('first-param', 'second-param', 'third-param')
       expected that MyWorker would have [first-param, second-param, third-param]
queued
       got MyWorker having [first-param, second-param, third param]

Yeah I am really agree, I had the same problem ;)

A PR to update the matchers output would be welcome.
