Autoselect store when only one exists

[gonzaloebiz]

In the config page, when select the apikey and only one store exists to this apikey, autoselect this store

This is working one the user selects an api key from the dropdown, but when the api key is pre-selected, the solo store is no pre-selected. @gonzaloebiz can that be added?

If the user enter to the configuration and see that the store is selected, the user can thing that the store is already configured, so i don't think that is the better option

[lduh]

That makes sense.
