It prevent the problem that a TcManager is available even if not TcProvider
is able to create new graphs. In our traditional launcher this is addressed
with startlevels but I don't think that this is a good solution.

A problem that is still open is what if there is an in-memory TcProvider in
the system? I've had problems that graphs got created in this because the
TdbTcProvider was loaded later.

Ideally TcManager should wait for all TcProviders to be active, but I'm not
sure if an d how this can be done.
