Juju does not support setting owner label using secret-get

[Ian Booth]

Looking up a secret using a label is broke. Steps to reproduce from the CI test below.
The last line fails.
Looking at the db, there's no label recorded for the application owned secret in secret metadata.

 juju --show-log deploy easyrsa
 juju --show-log deploy etcd
 juju --show-log integrate etcd easyrsa

 secret_owned_by_easyrsa_0=$(juju exec --unit easyrsa/0 -- secret-add --owner unit owned-by=easyrsa/0)
 secret_owned_by_easyrsa_0_id=$(echo $secret_owned_by_easyrsa_0 | awk '{n=split($0,a,"/"); print a[n]}')
 secret_owned_by_easyrsa=$(juju exec --unit easyrsa/0 -- secret-add owned-by=easyrsa-app)
 secret_owned_by_easyrsa_id=$(echo $secret_owned_by_easyrsa | awk '{n=split($0,a,"/"); print a[n]}')

 echo "Set a label for the unit owned secret $secret_owned_by_easyrsa_0."
 juju exec --unit easyrsa/0 -- secret-set "$secret_owned_by_easyrsa_0" --label=easyrsa_0
 echo "Set a consumer label for the app owned secret $secret_owned_by_easyrsa."
 juju exec --unit easyrsa/0 -- secret-get "$secret_owned_by_easyrsa" --label=easyrsa-app

 # secret-get by label or consumer label - content.
 juju exec --unit easyrsa/0 -- secret-get --label=easyrsa_0 | grep 'owned-by: easyrsa/0'
 juju exec --unit easyrsa/0 -- secret-get --label=easyrsa-app | grep 'owned-by: easyrsa-app'
