Remove meta context vars in regular for loop

[jasmith-hs]

In eager execution, we'll use the default for loop logic first if the collection can be resolved so we need to remove the variables from the meta context variables as we do when running the EagerForTag's logic.

Basically, we weren't doing this when using the regular for loop's logic:

jinjava/src/main/java/com/hubspot/jinjava/lib/tag/eager/EagerForTag.java

Lines 187 to 190 in 8d879ea

	Set<String> removedMetaContextVariables = EagerReconstructionUtils.removeMetaContextVariables(
	loopVars.stream(),
	interpreter.getContext()
	);

Without this change, the eager execution output would look like:

{% for __ignored__ in [0] %}
  {% macro render(content, query) %}
    {% if query %}
      {{ content.foo }}
    {% endif %}
  {% endmacro %}
  {{ render(content, deferred) }}
 // repeated
{% endfor %}

content would not be reconstructed since it would remain considered a meta-context variable, but we need to temporarily remove that status when rendering a for loop {% for content in looper %}
