bug#12721: 24.2; package-installed-p behavior on emacs startup

[kostafey]

How the function package-installed-p should behave on emacs startup if

some package is already installed? It seems that it returns nil for

installed package on emacs startup.

Here is the full .emacs file (used for this test):

(require 'package)

(message "**** auto-complete is installed: %s ****" (package-installed-p 'auto-complete))

auto-complete package is installed for this moument, but during emacs

sturtup *Messages* buffer shows:

**** auto-complete is installed: nil ****

But after sturtup the evaluation of the _expression_

(message "**** auto-complete is installed: %s ****" (package-installed-p 'auto-complete))

returns:

**** auto-complete is installed: t ****

But how it is possible to install just not already installed packages on

startup. For this moument all packages are re-downloaded and reinstalled

for me during every emacs startup.
