closes#11932
- as per the issue, there is no need to output a <link> tag if the favicon is the default /favicon.ico, as all browsers automatically check for this
- instead the favicon <link> is only output if a custom favicon has been set, telling the browser to look somewhere different to its default location
- some of the tests expected 3 links in the html head, but through the favicon change there are often only 2.
