fix(view): render falsy and truthy data attributes

[innocenzi]

Another day, another Tempest View improvement in sight!

This pull request adds failing tests for rendering truthy and falsy attributes in an expected way:

<div :data-active="true"></div>
<!-- Should render: <div data-active></div> -->

<div :data-active="false"></div>
<!-- Should render: <div></div> -->
