fix: cleanup inconsistent and incorrect import error handling

Some notified errors didn't include error object. Import cli didn't fail
on failure and stack was reversed. Error notifications sometimes
included full error which makes errors unreadable in CLI and possibly
confusing for users. Also fixed missing classpath. Part of
