notes: do not trigger editor when adding an empty note
With "git notes add -C $blob", the given blob contents are to be made
into a note without involving an editor. But when "--allow-empty" is
given, the editor is invoked, which can cause problems for
non-interactive callers[1].
This behaviour started with 90bc19b3ae
(notes.c: introduce
'--separator=<paragraph-break>' option, 2023-05-27), which changed
editor invocation logic to check for a zero length note_data buffer.
Restore the original behaviour of "git note" that takes the contents
given via the "-m", "-C", "-F" options without invoking an editor, by
checking for any prior parameter callbacks, indicated by a non-zero
note_data.msg_nr. Remove the now-unneeded note_data.given flag.
Add a test for this regression by checking whether GIT_EDITOR is
invoked alongside "git notes add -C $empty_blob --allow-empty"
