Fix/format code error details

[sbke-mms]

Description

fixes: code view in error details is displayed properly formatted
fixes: HTML in error messages no longer gets rendered -> this was an issue with Selenium exceptions that included part of the html code where the exception occured.
As a result of this fix URLs that were added to error messages only get displayed as plain text and not as links.

Is that relative path needed?

At least IDEA complains about not finding the old one. Not quite sure whether SASS adds magic, but as far as I know, pathes have to be absolute or relative but not "module-like" like for EcmaScript modules.

So, looks sensible to me. Even if it still worked without, I'd deem it sufficiently minor to consider appeasing the IDE a sufficient reason.

Reverted this change since aurelia or something else seems to resolve this properly.
