[RFC PATCH v2 03/12] t7411: be nicer to future tests and really clean things up

[Antonio Ospite <ao2@ao2.it>]

Tests 5 and 8 in t/t7411-submodule-config.sh add two commits with
invalid lines in .gitmodules but then only the second commit is removed.

This may affect future subsequent tests if they assume that the
.gitmodules file has no errors.

Since those commits are not needed anymore remove both of them.

The modified line is in the last test of the file, so this does not
change the current behavior, it only affects future tests.

Signed-off-by: Antonio Ospite <ao2@ao2.it>

Note that test_when_finished is not used here, both to keep the current style
and also because it does not work in sub-shells.
