Prevent prepending single quote to issue CSV exports

What does this MR do?

Only prepend single quote to CSV exported field when unpermitted chars are at the beginning of the string.

In the current behaviour if any unpermitted char is found after a line break a single quote is inserted
breaking the markdown. For example:

This description

- [ ] has a task list

Becomes 'This description\n- [ ] has a task list.

This behaviour got introduced on a security fix(internal only).
