Attributes in macros are double quoted

[mortona42]

• this is using aleksip/plugin-data-transform for attributes

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.
