[PATCH 1/2] t3412: clean up GIT_EDITOR usage

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

a6c7a27 (rebase -i: correctly remember --root flag across --continue,
2009-01-26) introduced a more portable GIT_EDITOR usage, but left the
old tests unchanged.

Since we never use the editor (all tests run the rebase script as
proposed by rebase -i), just disable it outright, which simplifies the
tests.
