[PATCH 1/2] t3301: test diagnose messages for too few/many paramters

[Doan Tran Cong Danh <congdanhqx@gmail.com>]

From commit bbb1b8a35a, ("notes: check number of parameters to "git
notes copy"", 2010-06-28), we have a test for too many or too few
of parameters provided to `git notes copy'.

However, the test is only ensure the command will fail but it doesn't
really check if it fails because of number of parameters.

If we accidentally lifted the check inside our code base, the test may
still failed because the provided parameter is not a valid ref.

Correct it.
