erp5: bootstrap software instance test

with minimal tests to reproduce the issue that instanciation is broken
when no test runner.

note that we don't put tests in "one big test.py", but from the
beginning we separate so that we can put test for each software type in
test/test_$(software type).py and test for default software type in
test/test_erp5.py
