Add Behat test for pathauto behavior

testing this patch at the sprint

The last two lines will fail due to a bug with permalink that is preventing the redirect:

Given I go to "testing-title"
Then the response status code should be 301

I haven't found an issue for this bug yet, but if I can't I will create one and link it. However, these two lines SHOULD be put back into this test once that bug is fixed as it would be correct to test for that behavior. I will not this and link back to this issue in the issue for the permalink bug.

Also, on line 35 of the patch:
Then the response status code should be 200
Inside the "Scenario: Pathauto should keep old url when changing the title"
The response code should be a 404 as changing the title should not change the path. Therefore, going to "completely-other-title" should cause a 404 not a 200.
I am creating a patch to reflect these changes.

Here is the patch!

@carsonblack: Thanks! It works for me, so - committed. :-)

Can you make a new issue describing the bugs with panopoly_admin interfering with Pathauto that we investigated at the sprint? Thanks!

There appears to be a legitimate failure when updating from 1.0-rc3:

https://travis-ci.org/panopoly/panopoly/jobs/27016765

I haven't had a chance to look into it, but I assume it's some Pathauto setting thats setup by default on 1.0-rc4 and later, but not set in a hook_update_N() function.

I've made a new issue for this:

#2282833: Pathauto tests failing after update from 1.0-rc3

I have created issue 2283223 which covers the permalink redirect bug.

@dsnopek I think this could be related to not setting the Update Action setting in pathauto to "Create new alias. Leave the existing alias functioning". I mention this in Issue# 2283223.

Thanks, Carson!
