fix(tag): onclick handler cannot be set undefined

HCRC-178.

The Tag onClick handler should be undefinable, because it also affects
to the Tag styling, by adding border, if there is an onClick handler.
Also, the onClick decorator that we were using, was totally needless, so
now the HDS Tag onClick property is used directly instead.
