Update manifest errors in list component should not be returned, change to warning

[c4pt0r]

Update manifest errors in list command should not be returned, change to warning

Reason:

1. If the manifest is already available locally, the local component
   should be listed, but output warning

2. If there is no local manifest, in case of update manifest error,
   init manifest will also fail and will not continue
