fix: regression with unquoted attribute with trailing slash, revert bogus comment minification #1561

Description

#1557 made it so that Marko would omit quotes around attributes that did not contain any invalid characters. However this added a regression for the last attribute if it had a trailing slash, ie:

<a rel=external href=http://ebay.com/>
  Go!
</a>

If the href attribute was first, it would actually parse correctly, however the ambiguity above means that the <a> is closed too early which caused the regression.

The fix in this PR is to add a space if the unquoted attribute has a trailing slash.

This PR also reverts the comment minification from that PR. Although there was no regressions with that, and it is objectively smaller output, it does cause html linters and validators to complain. This may appear in a future version of Marko, but we need to re-evaluate.
