fix(issue): name missing issues and attachments in errors

tea issue close 999 printed "issue 999: not found (HTTP 404 GET …)" and
issue attachment view 1 9 blamed issue #1 for a missing attachment.
Batch commands (issue close, reopen, edit, milestone issue add and
remove) now report "issue 999: not found in alice/x", and attachment
commands "attachment 9 not found in alice/x#1".
