[IMP] orm: removed partial validation of default_focus attribute in fields_view_get

It was not correct. and even doing it with XPath is difficult because of nested form views etc.
It is easier to have the clients gracefully handle cases where too many default_focus attributes are set instead - just taking the first one is fine
