Handlebars special partial "@partial-block" gets reported as unknown global

[miko007]

Issue Summary

The handlebars template engine provides an internal, special partial called @partial-block, that can be used when calling a partial in "block style".

Instead of calling the partial regularly like {{> my-partial}}, it can be called in block form like

{{#> my-partial}}
  some fallback text
{{}/my-partial}

Inside the partial, the content passed inside the block can then be accessed using the special partial {{@partial-block}}. The feature itself works like expected inside of a ghost theme, the usage gets however reported as a theme error, specifically as "{{@partial-block}} is not a known global". This should not be the case.

Steps to Reproduce

1. put a partial with the content

<div>
   fancy partial
     {{#if @partial-block}}
	<article>
		{{> @partial-block}}
	</article>
     {{/if}}
</div>

in a theme.

2. call it like

{{#> my-partial}}
   this is a fallback text
{{/my-partial}}

3. check backend for theme errors
