[PATCH v2 2/2] commit: remove irrelavent prompt on `--allow-empty-message`

[Hu Jialun <hujialun@comp.nus.edu.sg>]

Even when the `--allow-empty-message` option is given, "git
commit" offers an interactive editor session with prefilled
message that says the commit will be aborted if the buffer is
emptied, which is wrong.

Remove the "an empty message aborts" part from the message when
the option is given to fix it.

The tests are also amended in line with the new string.
