erp5_catalog: Update testCopySupport according to changes in portal_catalog

Its better to change the tests where they need to call getpath function of
portal_catalog to use portal_catalog.getpath instead of portal_catalog.getPath,
as we have overridden the 'getPath' function for CatalogTool class due to change
in inherited class.
