Call buildCssPath with empty string for default template (#3594)

* Call buildCssPath with empty string for default template

Call buildCssPath with an empty string instead of null for the default template

* Remove unused options argument

This means we can also remove the empty strings for the themeModifier arg,
instead passing undefined, to get the default arg
