chore: Re-enable checking broken links in sponsors section (#2372)

- Earlier the test was on FossasiaSummit2017 in which one sponsor link was broken so the test failed
- Now we are checking for MozillaAllHands2017 so the test is moved after eventPage visits the MozillaAllHands2017 site

Fixes #2362
