make '-min' minimize wallet loading dialog

[furszy]

Simple fix for #748.

When '-min' is enabled, no loading dialog should
be presented on screen during startup.

I've tested this change. Created several wallets in order to see the "Loading wallet..." dialog for a while.
Without your change in master when I run bitcoin-qt -min the dialog is not shown and the app opens as usual.
With your change when I run bitcoin-qt -min, the app gets minimized entirely, is that intentional?

Yes. Thats the -min flag purpose: start the app minimized.

The bug did not reveal itself on my Ubuntu + GNOME.

FWIW, a user on #bitcoin IRC mentioned today that this patch wasn't backported to v25.x.
