closes #10531 - Adds space when encountering closing </p> and <br> tags - The mobiledoc-to-html conversion produces these tags in this exact syntax, so there is no need to account for more cases like additional spaces or alternative syntax like <br /> - Added test cases that cover spacing use-casei - Changed some existing tests to contain more close-to-real-world markup - The downside of this approach is generating multiple spaces in case there are empty paragraphs in the markup. The same concern is true for current "new line" substitution: > excerpt.replace(/(\r\n|\n|\r)+/gm, ' ') but it never has been a concern as in real world when multiple spaces are used inside of the `<p>` tag they are rendered as single space.
