Mailto links: invalid email address trailing part should not be linkified

[vincent-vignaud]

For example, mailto:toto@example.com:123 is linkified (linkifyjs/string) as:
<a href="mailto:toto@example.com:123" class="linkified">mailto:toto@example.com:123</a>.

The value of the href attribute and the value of the text node both contain an invalid email address toto@example.com:123.

Since the colon character : is not allowed* in the domain part of the address (unless being an IP address between brackets), the part :123 should not appear in the href attribute nor in the text node.

Same issue with other invalid characters*, for example mailto:toto@example.com<123 becomes <a href="mailto:toto@example.com<123" class="linkified">mailto:toto@example.com&lt;123</a>.
