As of now, link-tracking creates link tracking for every <a> tag, no matter the href attribute. This commit only creates link tracking for valid URLs. The reason I wrote a new regex instead of rewriting linkTagRegex is that this regex is used by message-list. https://regex101.com/r/jD5zC7/3 vs https://regex101.com/r/cK0zD8/2 Resolves: #1525
