Fix an issue in the vim-plugins-updater where it was trying to access the
'normalized_name' attribute on an HTTPResponse object, causing the updater
to crash with:
AttributeError: 'HTTPResponse' object has no attribute 'normalized_name'
The fix adds type checking to ensure we only access normalized_name on
Plugin objects, and properly handle other types like Exceptions and
HTTPResponse objects.
