Always auto name and create new workspaces from oldDot

[timszot]

@TomatoToaster pinging you for review since we discussed this PR.

Details

Removes the workspace/new page completely since we always want to auto name and create workspaces for N6.
Slack thread for more context, but in N6 we always want to auto name and create the workspace for the user, so the workspace/new page is no longer needed.

Also removed the success growl per this issue.
