notes: send "Automatic notes merge failed" messages to stderr

All other error messages from notes use stderr.  Do the same when
alerting users of an unresolved notes merge.

Fix the output redirection in t3310 and t3320 as well.  Previously, the
tests directed output to a file, but stderr was either not captured or
not sent to the file due to the order of the redirection operators.
