[app code check] add OC_Search_Provider and _Result

Do not show static share owner if not available

expose the mount manager in the public api

owner is stored as 'uid_owner', not as 'owner' in the oc_share table

Fix global app list state

remove duplicate ID in HTML template for public shares

Do not register JS share plugin if core sharing API is disabled

In some corner cases, an outgoing share exists but sharing is not
allowed for the current user. This would cause the file list to break
because the static text could not be rendered as the owner was
undefined.

call post_addToGroup als for class OC_User because sharing and LDAP are using this class. Minimal approach to fix #16740

Thanks to @libasys for noticing this.

While making the AppStore ready for 8.1 I also deleted some dummy entries which means that these IDs do not resolve anymore. We should remove them to prevent errors such as https://github.com/owncloud/core/issues/17307
