dispatch: move command line --config argument parsing to _runcatch()

Previously, command line parsing of --config arguments was done in
_dispatch. This means that it takes place after activating the debugger. In an
upcoming patch, we will add a ui.debugger setting so we need to have this
parsing done before _runcatch.
