Attributes in macros are double quoted

[mortona42]

This is cross-posted at pattern-lab/patternengine-php-twig.

This is working fine in a pattern:
<div {{ attributes.addClass('test') }}>test</div>
<div class="test">test</div>

But if this is inside a macro, I get:
<div class=""test"">test</div>

I can work around this by including the macro file like another pattern.

I have twigAutoescape: false as per #18.

Thanks for the bug report! Will look into this as soon as I find some time.
