test-obsolete: use 'log -T {node}' instead of 'id --debug -i' to lookup hash
I ran into a case when adding a test where there were cryptic hg command line
errors. I eventually traced it back to 'hg id' printing debug messages before
the hash:
invalid branchheads cache (served): tip differs <hash>
This method should eliminate any other output except the node.
