The tag owner cannot be null or empty

[mdavidsaver]

I'm not sure if this is a phoebus issue or a service issue. I'm reporting here first on the theory that this still works with the original service.

Attempting to apply a tag through Channel Table fails. I don't see any obvious error in the phoebus log, but the service shows the following. From my recent playing around I recognize this as omitting the "owner" tag somewhere.

imo. it is annoying having always to include "owner" everywhere, even in places when I don't want ownership to change. eg. twice to apply a tag.

{"owner":"admin","name":"atag","channels":[{"name":"bar","owner":"admin"}]}

And three times to apply a property.

{"owner":"admin","name":"aprop","channels":[{"name":"bar","owner":"admin","properties":[{"name":"aprop","value":"foo","owner":"admin"}]}]}
