lei q: fix JSON overview with remote externals

We can't (and don't need to) repeatedly get the $each_smsg
callback for each URI since that clobbers {ovv_buf} before
it can be output.

I initially thought this was a dedupe-related bug and
moved the dedupe code into the $each_smsg callback to
minimize differences.  Nevertheless it's a nice code
reduction.

I also thought it was related to incomplete smsg info,
so {references} is now filled in correctly for dedupe.
