fix -DhscriptPos support in ConsoleUtil.hx (HaxeFlixel#1840)

With hscript version >= 2.0.5 compiling with -DhscriptPos gives compilation error:
flixel/4,0,1/flixel/system/debug/console/ConsoleUtil.hx:156: characters 9-42 : Class<hscript.Error> has no field EInvalidAccess

The proposed fix uses the error() method now defined in hscript's Interp class (following usage in hscript's Interp.hx)
