call _test_step instead of test_step in Bundle easyblock

[Thyre]

(created using eb --new-pr)

Partially addresses #4044.
The Bundle easyblock can now correctly handle --ignore-test-failure, but renaming the function on the framework level is still the better option in the long run...

For testing, I've added this diff to X11:

It's worth noting that this naming change shows up in the logs:

But I think this fix is worth having this slight change in the logs. We could still improve this by doing some string manipulation to replace a leading _ in the step_name in the case of _test_step. Currently, we just pass the step_name again.

comp.run_step(step_name, [lambda x: getattr(x, '%s_step' % step_name)])
