Can't print a Triple pattern, e.g. when debugging #2

A Triple with one or more nulls is a Triple pattern. I found that I couldn't print a pattern, e.g. using puts during debugging, because inspect calls to_n3 which checks for any nil values in s, p or o. The error I get is:

RdfContext::RdfException: Can't serialize pattern triple
'RdfContext::URIRef[<http://example.org/foo>, ns=nil], 
RdfContext::URIRef[<http://example.org/p>, ns=nil], nil'
from /var/lib/gems/1.9.1/gems/rdf_context-0.5.5/lib/rdf_context/triple.rb:41:in `to_n3'

Thanks for the report, I'll look into it shortly. I have a couple of other changes I'd like to get in too.
