Markup Regions: pw-optional region not removed when template file has no regions

[Toutouwai]

Short description of the issue

This issue is similar to an earlier fixed issue: #302

pw-region elements were fixed but the same kind of fix is needed for pw-optional elements. Empty pw-optional elements still need to be removed even if a template file does not contain any region markup.

Steps to reproduce the issue

1. Include an empty element in _main.php that has the pw-optional attribute.
2. Do not include any region markup in the basic-page.php template file.
3. Check the rendered source code for any basic-page and note that the empty element with the pw-optional attribute is present.

Setup/Environment

• ProcessWire version: 3.0.153
