previously multi-line property does not effect <ps> tag.
now <ps> is treated visually like <br> when multiline is set to EINA_FALSE
this issue was that each new paragraph will create new line regardless of multi line property value, now only first paragraph will create new line if multi-line property is false, and other paragraphs will use same line
this will also fix the following patch https://phab.enlightenment.org/D8603
And both will use same test suite code
