xray breaks Jasmine tests if jasmine-jquery is included

[mackuba]

There's a part of code that tries to find jQuery asset on the list and insert xray right after it. Unfortunately, it also matches jasmine-jquery, which happens to be included before jquery itself in my case, so xray loads before jQuery and some things don't work as they should.

I think the regexp should be updated so that it only matches assets that actually start with the asset name after a quote or slash.
