get_cart_total() should honor the 'tax_display_cart' option

If prices are entered without taxes (prices_include_tax == false) and the option 'tax_display_cart' is active (tax_display_cart == true), the method should return the gross total.

Theme in use: flatsome
Error appears: cart contents in the top right corner shows net prices although 'tax_display_cart' is active. It's currently the only place in my shop where net prices are displayed.
