[UI] Text copied from log view has no newlines

[Conrad Hoffmann]

In MAAS 2.6.0 (7802-g59416a869-0ubuntu1~18.04.1), when copying text from the log view (both controller as well as machine logs), the entire text is just one single long line, which makes it very hard to supply output for bug reports or other investigations.

Tried with both Firefox and Chrome, didn't seem to make a difference. I noticed that the log is rendered by making each line a <span> with some CSS magic, I suppose that's part of the problem.

Especially in combination with https://bugs.launchpad.net/bugs/1820753 (no direct download of logs) this makes for some cumbersome debugging sometimes :)
