tests: import multiple modules separately
Current import-checker.py overlooks code fragment changed in this
patch, because of restrictions below for a line starting code
fragment.
- filename must be specified before limit mark
NG: cat <<EOF > FILE.py
OK: cat > FILE.py <<EOF
- limit mark must not be quoted
NG: cat > FILE.py <<'EOF'
OK: cat > FILE.py <<EOF
import-checker.py itself is fixed in subsequent patch.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
