[BUGFIX] Do not show exeption when folder is not accesible

When a storage folder is not accessible for the user a exception
is displayed. Same if the folder is missing.

This patch changes the exception to
\TYPO3\CMS\Core\Resource\Exception.

The user will get a flash message and FAL tries to display the
parent folder of the restricted folder. If the folder is
missing the parent folder is displayed.
