ListItem Partials Render with Previously Found Partial's StyleModifier

[bmuenzenmeyer]

I am using Pattern Lab Node v2.0.0 onWindows, using thegulp` edition.

Found on a private instance of PL/Node 2.0.0 in prep for WDD 2016.

Expected Behavior

Running blockset.mustache

<section class="blockset {{#vertical}}blockset__vertical{{/vertical}}">
  {{> molecules-block }}
{{#listItems.three}}
  {{> molecules-block }}
{{/listItems.three}}
</section>

should emit blocks with no styleModifier using this pattern

block.mustache

<div class="block {{styleModifier}}">
  {{> atoms-picture }}
  {{> atoms-paragraph }}
</div>

Actual Behavior

Actual output includes the previously found molecules-block with the styleModifier class added.
since this was already parsed

block-hero.mustache

{{> molecules-block:block__hero }}

was already parsed and is polluting this list item parsing.

We have a bunch of unit tests covering pattern parameters, but either regressed or omitted styleModifiers.

Feels like a regression of #190
