command/e2etest: fix incorrect "terraform version" test
command/e2etest: fix incorrect "terraform version" test

Two different errors here caused this test to pass even though it was
incorrect: the wanted version string was incorrect, but the test for it
was also inverted, and so together this made the test pass even though
it was actually not testing the output at all.
