bug#20355: 25.0.50; Package installation fails without a fully loaded init file

[Jorgen Schaefer <contact@jorgenschaefer.de>]

Hello!

I recently accidentally uninstalled a package required by my init.el.
The result was that starting Emacs failed. I then could not install the
package again, though, as package-install failed with an error "the init
file was not fully loaded". I suspect the latter is from the attempt to
set `package-selected-packages'. The same error happened when I started
Emacs with -q.

I would expect to be able to install packages without error if I start
Emacs with -q, or indeed if my init file breaks.

Thanks!

Jorgen
