Error when using plain text wrapper and inline css together

Problem/Motivation

When the *all* policy is set to use html email with inline css, a policy targeting a specific sub type with the Wrap and convert adjustment set to 'plain text only', the following error is thrown:

 [error]  ValueError: DOMDocument::loadHTML(): Argument #1 ($source) must not be empty in DOMDocument->loadHTML() (line 116 of /Users/loze/Sites/hsc-mig1/vendor/tijsverkoyen/css-to-inline-styles/src/CssToInlineStyles.php) #0 /Users/loze/Sites/hsc-mig1/vendor/tijsverkoyen/css-to-inline-styles/src/CssToInlineStyles.php(116): DOMDocument->loadHTML('')

What Im trying to achieve is all my emails to be sent as html with inline css, except for one specific sub type, which I want to be plain text

Proposed resolution

If Wrap and Convert is set to plain text only, skip the inline css process that may be set on a parent policy.
