Despite it's PHPDoc the function might return `null` which was not properly catched and thus in some situations the share was resolved to the sharing users root directory. To test this perform the following steps: * Share file in owncloud 7 (7.0.4.2) * Delete the parent folder of the shared file * The share stays is in the DB and the share via the sharelink is inaccessible. (which is good) * Upgrade to owncloud 8 (8.0.2) (This step is crucial. The bug is not reproduceable without upgrading from 7 to 8. It seems like the old tokens are handled different than the newer ones) * Optional Step: Logout, Reset Browser Session, etc. * Access the share via the old share url: almost empty page, but there is a dowload button which adds a "/download" to the URL. * Upon clicking, a download.zip is downloaded which contains EVERYTHING from the owncloud directory (of the user who shared the file) * No exception is thrown and no error is logged. This will add a check whether the share is a valid one and also adds unit tests to prevent further regressions in the future. Needs to be backported to ownCloud 8. Adding a proper clean-up of the orphaned shares is out-of-scope and would probably require some kind of FK or so. Fixes https://github.com/owncloud/core/issues/15097
