fix: list every project in template/image in-use refusal, not just the first

Browse Source 
The usage scans broke out of the whole (project, node) iteration at the
first matching node, so deleting a template or image used by several
projects reported only one project name while the error message says
'one or more projects'. Keep scanning and list each project once.

Caught on a live server: an IOU L3 template used by two projects
(one of them closed) was refused citing only one of them.
