[PATCH] test suite: remove useless TERM cruft in "t7005-editor.sh"

[Christian Couder <chriscool@tuxfamily.org>]

In commit 15387e32ff5116b82d3fe53df55b8c87eec83e01 I added some cruft
to reset TERM to its previous value before the "test_done" at the end
of "t7005-editor.sh" because otherwise "test_done" would have printed
the test result with a bad TERM env variable (this resulted in output
with no color on konsole).

But since commit c2116a1783a3d555d41892ae7db0dd0934d4ddf1 colored
output is printed in a subshell with TERM reset to its original value
so the cruft added in my patch above is now useless.
