Subject: [PATCH] Turn obsolete error into warning (#3172)

* query/query.go: turn obsolete error into warning

The default value logic obseleted this error. When generating the output graph
we already have all the values necessary. This error was when we needed to match uidToVal
to NeedsVar.

* query/query.go: remove info log
