bug#20930: 25.0.50; Package archive priorities not honored for upgrades

[Artur Malabarba <bruce.connor.am@gmail.com>]

Small sanity check. What are your values for the variables
`package-menu-hide-low-priority' and `package-menu--hide-packages'?

>
> Steps to reproduce:
>
> 1. Start emacs -Q
>
> 2. configure-group package
>
>  -  Add melpa and melpa-stable to package-archives:
>
>     (("gnu" . "http://elpa.gnu.org/packages/")
>      ("melpa-stable" . "http://stable.melpa.org/packages/")
>      ("melpa" . "http://melpa.org/packages/"))
>
>  -  Set priorities with melpa-stable highest:
>
>     (("melpa-stable" . 20))
>
> 3. list-packages and install something from melpa-stable for which there
> is a newer version on melpa. In my test: ace-jump-mode v2.0.
>
>   ace-jump-mode      2.0           installed
>
> 4. Check for upgrades; get prompted to upgrade to melpa version:
>
> I ace-jump-mode      20140616.115  available  melpa
> D ace-jump-mode      2.0           installed
>
> Since melpa has priority 0 and melpa-stable has priority 20, I would
> expect this upgrade not to be included. In my current setup I have a
> dozen or so packages from the gnu and melpa-stable archives and am
> prompted to update all of them.
