Jonas Schürmann 4a9f4ba5eb Fix vector-im/riot-web#6523 Emoji rendering destroys paragraphs ...

This regression was probably introduced in
4f4441fb07 and is caused by the fact that
the variable `isHtml` conflates two different meanings:

- The event contains an HTML message
- The event message is displayed using HTML

This is an important difference. Plain text messages that contain
emojies are rendered with an HTML string and thus have to be sanitized
etc. But they must not use the MarkDown CSS styles for HTML messages.

The MarkDown CSS styles include `whitespace: normal` because HTML events
use `<br/>`-tags for line breaks. Plain text messages with emojies
obviously don't use `<br/>`-tags, so these styles must not be applied.
