Remove arbitrary references to ChromeShell in comments.

Remove arbitrary references to ChromeShell in comments.

Since ChromeShell is going away, we shouldn't reference it in examples
in comments. This updates those comments to use something else as an
example.

Also, removing these references makes it easier to grep for the real
remaining uses of ChromeShell in the codebase.

this line is a copy-paste mistake and should never have been here

We're still using ChromeShell for waterfall testing with ChromeDriver, but we'll
be replacing this shortly with ChromePublic.
