🐛 font inputs rendered twice fix

In the Settings > Appearance> Font tab, the input fields for body and header fonts were getting rendered twice.  We had duplicate code in two different files that called fontselect() on both elements. Because JS was getting called twice, two input fields were displayed. Removing one of them resolves the issue.
