[BUG] Problem with mine.get in state

[johje349]

Description
After upgrading to 3001 one of my states started to fail with "Jinja variable list object has no element 0"

Setup
I narrowed it down to a simple test:

{% for sourceHost, sourceIp in salt['mine.get']('*', 'network.ip_addrs', 'compound').items() %}
isList: {{ sourceIp | is_list }}
sourceIpList: {{ sourceIp }}
sourceIp: {{ sourceIp[0] }}
{% endfor %}

Running salt-call state.apply test:

[ERROR   ] Rendering exception occurred
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/salt/utils/templates.py", line 400, in render_jinja_tmpl
    output = template.render(**decoded_context)
  File "/usr/lib/python3/dist-packages/jinja2/environment.py", line 989, in render
    return self.environment.handle_exception(exc_info, True)
  File "/usr/lib/python3/dist-packages/jinja2/environment.py", line 754, in handle_exception
    reraise(exc_type, exc_value, tb)
  File "/usr/lib/python3/dist-packages/jinja2/_compat.py", line 37, in reraise
    raise value.with_traceback(tb)
  File "<template>", line 4, in top-level template code
jinja2.exceptions.UndefinedError: list object has no element 0

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/salt/utils/templates.py", line 166, in render_tmpl
    output = render_str(tmplstr, context, tmplpath)
  File "/usr/lib/python3/dist-packages/salt/utils/templates.py", line 407, in render_jinja_tmpl
    raise SaltRenderError("Jinja variable {0}{1}".format(exc, out), buf=tmplstr)
salt.exceptions.SaltRenderError: Jinja variable list object has no element 0

Now if I replace '*' as target with a hostname I get the expected result:

{% for sourceHost, sourceIp in salt['mine.get']('asx-salt', 'network.ip_addrs', 'compound').items() %}
isList: {{ sourceIp | is_list }}
sourceIpList: {{ sourceIp }}
sourceIp: {{ sourceIp[0] }}
{% endfor %}

Running salt-call state.apply test
[DEBUG   ] Rendered data from file: /var/cache/salt/minion/files/base/test/init.sls:

isList: True
sourceIpList: ['10.133.45.67']

@johje349 Does this give you the same result as state.apply? salt-call cp.get_template salt://test/init.sls /tmp/foo && cat /tmp/foo
