[Devtools] Removed timeline setting from network log settings

This patch ensures there are no lingering "timeline" setting for network
log settings. "timeline" or "waterfall" may have been saved into the
users settings and when the new waterfall came out it may have caused
some users to see "timeline" as a custom column; this removes that.
