[PATCH 06/18] notes.c: Use two newlines (instead of one) when concatenating notes

When using combine_notes_concatenate() to concatenate notes, it currently ensures exactly one newline character between the given notes. However, when using builtin/notes.c:create_note() to concatenate notes (e.g. by 'git notes append'), it adds a newline character to the trailing newline of the preceding notes object, thus resulting in _two_ newlines (aka. a blank line) separating contents of the two notes.

This patch brings combine_notes_concatenate() into consistency with builtin/notes.c:create_note(), by ensuring exactly _two_ newline characters between concatenated notes.

The patch also changes a few notes-related selftests accordingly.
