With Fluid 2.12, we introduced the ability to provide arbitrary
ViewHelper arguments to TagBasedViewHelpers. Consequently,
we deprecated the method registerTagAttribute(), which is no
longer necessary due to the mentioned change.
However, the implementations differed until now: The previous
implementation ignored empty strings for tag attributes, while
the new implementation added such input as empty attribute
to the resulting tag. We now check for empty strings and only
add attributes to the tag if it's not an empty string.

This will be backported to Fluid 2.14.
