[PATCH 3/4] t3301: fix confusing test for valid notes ref

[Thomas Rast <trast@student.ethz.ch>]

The test used single quotes in the test code, but also single quotes
to wrap the entire test snippet, thus effectively skipping _out_ of
quoted mode.  Since it doesn't matter here, just drop the quotes to
cause less confusion.

Also, the test passed a MSG variable to 'git notes show', but that
never calls an editor.

Signed-off-by: Thomas Rast <trast@student.ethz.ch>

As an aside, is there a specific reason why all the negative tests use
'! VAR=foo bar' instead of 'VAR=foo test_must_fail bar'?  I thought
the latter was preferred to catch segfaults.
