[PATCH] t7406: fix i18n expectation of error message

[Stefan Beller <sbeller@google.com>]

The error message from "submodule update" is internationalized, which
makes sense. The test however did not check for the translated version,
but used a hardcoded string, which breaks the test when run with
GETTEXT_POISON.
