Subject: return only the one applicable OU setting value
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=b1be1ab9d3f6032e76cf3b519abe21d9cc476dae;p=working%2FEvergreen.git

return only the one applicable OU setting value

Correct actor.org_unit_ancestor_setting so that it returns
at most one setting value, rather than the entire set
 of values defined for the OU and its ancestors.
