Themes: Avoid unnecessary check whether parent template file exists when not using a child theme. 

Prior to this change, the `locate_template()` function would unconditionally check whether the relevant template file exists in the parent theme, which for sites not using a child theme is an exact duplicate of the previous check. This is wasteful and has a small impact on performance since `file_exists()` checks have a cost.
