Fix test to fail on incorrect input

[LenaBarinova]

In 'Waypoint: Add Font Awesome Icons to our Buttons' challenge changed a test to check whether element is within Like button (did it the same way as it is done in 'Waypoint: Add Font Awesome Icons to all of our Buttons' challenge).
closes #4981

Don't you need to do the prior test as well as the new test? It looks like you're testing to make sure it's in a button, but now it could be any button, not just the like button.

[LenaBarinova]

I'm checking the button of a class .btn-primary, which is our like button's class.

[SaintPeter]

Yes, but the example was someone creating a whole new button. If they could do that, they could create a copy of the button's classes as well.

Maybe I'm being over sensitive. @ltegman, @bugron ?

[bugron]

Agreed with @SaintPeter. We need both of these tests. You can combine them: $(\"i.fa-thumbs-up\").parent().text().match(/Like/gi) && $(\".btn-primary > i\").hasClass(\"fa fa-thumbs-up\") or just left first test case unchanged and add second one with $(\".btn-primary > i\").hasClass(\"fa fa-thumbs-up\"). Being more precise is better.

[bugron]

@LenaBarinova OK, but now your second test checks for the Link text too. Remove $(\"i.fa-thumbs-up\").parent().text().match(/Like/gi) && from your second test, then run these commands:

git add .
git commit --amend

and then force push your branch to your fork: git push -f YOUR_ORIGIN YOUR_BRANCH_NAME.

I've appended the test, didn't create new one, since we are checking the same logical thing - fa-thumbs-up icon should be located within the Like button.

[bugron]

@LenaBarinova oh, yes, sorry, my fault.

[bugron]

@LenaBarinova I've verified that this works. After you squash your commits into one I'm ready to merge your PR.
Update: @LenaBarinova thanks a lot, verified and merged!

[LenaBarinova]

@bugron all done!

[LenaBarinova]

@bugron Thanks for the help! It was first commit, I hope further commits will go more smoothly :)
