Fix method signature mismatch in screen discovery to use getScreenInfoList instead of getScreenInfo

This resolves the error: 'No signature of method: org.moqui.impl.screen.ScreenFacadeImpl.getScreenInfo() is applicable for argument types: (String)' that occurred when trying to discover subscreens for screens like component://PopCommerce/screen/PopCommerceAdmin/Shipment.xml. The fix changes calls from getScreenInfo() to getScreenInfoList() which is the correct method available in ScreenFacadeImpl.
