Subject: Protect against empty lists of linked bib searches
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=4e1432dc5f5c1f0353b7a02564b555367366e3e7;p=evergreen%2Fjoelewis.git

Protect against empty lists of linked bib searches

Instead of returning undef when passed an empty list of bibs, always
return an array from
open-ils.cat.authority.records.count_linked_bibs
Apart from consistency, this prevents JS errors in the Manage
Authorities UI.
