Remove pointless reloading of UserConfig

It was added in 043cb2ea44, and the commit message was "reload config whenever
returning to gui". I don't understand what this means; Run() is called exactly
once after startup, so it would just reload the config again for no reason.

We will add a real way of reloading the config whenever it has changed later in
this branch.
