Draft: fix(underline): underline handling that allows for run underline to o…

[palmer-cl]

• Allows for override of paragraph underlines with run underlines that contain no w:val.

Additional context based on my findings:

• Word may have <w:u> tags but does not express them as underlines if they have no val property
• The document sent via email has mostly all of the text underlined, but not expressed because at the run level the underlines have no val=single or any other type of underline
• So if on the paragraph you have <w:u val=single> but on a run you then have <w:u color='fff'> this underline should not be expressed

Pay close attention to:

• we swap the order of mark processing to process paragraph first, then run marks so that the run marks take precendence. I didn't see any ramifications but good to double check this.

Example p tag:

Closing this going to take a different approach
