Administration: Menu entry hidden until after cache cleared

I just installed the quiqqer/feed package via the store.
The installation failed due to limited php execution time. I then retried the installation via php quiqqer.php update which installed quiqqer/feed in version 1.0.

After opening the administration I could not find an entry for the module in the App-submenu:

I thought version 1.0 may have a bug so I switched to version dev-master in the composer.json and did a php quiqqer.php update again.

I still couldn't find an entry in the menu bar.

After clearing the QUIQQER-cache (via the administration) the menu entry appeared:

This should (probably) not happen and the cache for the menu entries should be cleared on update/installation of (new) packages.

I'm running QUIQQER in version dev-dev (commit 41a67818).
