Updates/corrections for appstore release

[ghost]

Hi,

there are currently two issues where at least one of them make the app not install-able via the oC internal appstore:

1. The appinfo/info.xml should contain the <ocsid>174671</ocsid> metadata
2. The archive at the appstore (https://apps.owncloud.com/content/show.php/Polls?content=174671) containing a folder named polls-0.6.0. This makes the app not install-able as a:

Archive does not contain a directory named polls

is shown when trying to enable the app. The appstore/ownCloud is expecting a folder just called "polls". Some instructions how to release such a version via github where posted here: owncloud/core#18116 (comment)

@RealRancor Could you please test again and close the issue if it works (or report if the problem still exists, of course)
