Winona portable items recipes not using builder_skill

In a previous update, all recipes requiring skill trees were modified to use builder_skill param instead of builder_tag. However, in recipes.lua, 

-- Winona portable versions of the basic machines
Recipe2("winona_catapult_item",			{Ingredient("sewing_tape", 1), Ingredient("twigs", 3), Ingredient("rocks", 15)},				TECH.NONE,				{builder_tag="portableengineer", nameoverride="winona_catapult", description="winona_catapult"})
Recipe2("winona_spotlight_item",		{Ingredient("sewing_tape", 1), Ingredient("goldnugget", 2), Ingredient("fireflies", 1)},		TECH.NONE,				{builder_tag="portableengineer", nameoverride="winona_spotlight", description="winona_spotlight"})
Recipe2("winona_battery_low_item",		{Ingredient("sewing_tape", 1), Ingredient("log", 2), Ingredient("nitre", 2)},					TECH.NONE,				{builder_tag="portableengineer", nameoverride="winona_battery_low", description="winona_battery_low"})
Recipe2("winona_battery_high_item",		{Ingredient("sewing_tape", 1), Ingredient("boards", 2), Ingredient("transistor", 2)},			TECH.NONE,				{builder_tag="portableengineer", nameoverride="winona_battery_high", description="winona_battery_high"})

-- Winona skill tree
Recipe2("winona_remote",				{Ingredient("transistor", 1)},																			TECH.NONE,		{builder_tag="portableengineer"})

these recipes use builder_tag, inconsistent with other recipes unlocked by skill trees.
