If creating a proxy fails, we will show an error using the
notification API. So we can remove the notification.exception call.
But modify the docs for ToolProxy.create so that future developers
will know they need to handle failures themselves.
Only show one, more helpful error instead of two non-helpful errors.
Don't show the 'no configured tools' message if there is a proxy there.
Return to the Tool configure page when editing a proxy if you came
from it.

Created a new admin page for managing LTI tool types within

URL.
