Respect argline passed into jinja renderer

[terminalmage]

Resolves #55124.

[terminalmage]

I just realized that I opened this PR against master. The goal is to have this fix in 2019.2.3, does it need to be rebased against a different branch for this?

Looks like there are some possibly related test failures?

Traceback (most recent call last):
  File "/tmp/kitchen/testing/tests/unit/utils/test_jinja.py", line 1492, in test_normlookup
    ret = self.render(tmpl_str)
  File "/tmp/kitchen/testing/tests/unit/utils/test_jinja.py", line 1483, in render
    return self.jinja(tmpl_str, context=context or {}, from_str=True).read()

TypeError: render_tmpl() got multiple values for keyword argument 'from_str'

The tests that were failing were failing because they were not designed properly. from_str is supposed to be derived from the argline, not passed in via the double-asterisk catch-all. I fixed the failing tests.

@terminalmage @waynew the windows failures look legit.

[terminalmage]

@dwoz I pushed an update to the tests, and rebased to bring it up to date with master.

@terminalmage looks like there are pending conflicts when you get time :) I'm updating the labels to next release so that it isn't confusing

[terminalmage]

Rebased again.

[terminalmage]

Rebased yet again. It has been 5 1/2 months since this PR was opened. It's a one-line code change, and was submitted with tests.

Can we please get this re-re-re-reviewed and merged?
