MB-48926 Delete mn.text.expander.html line breaks

The logs lines don't have an extra space anymore in the logs page.
Removing line breaks inside mn.text.expander.html file is necessary
because this component uses 'white-space: pre-line',
a CSS property which takes into account the line breaks written in HTML.
