Vincent Petry f6e644b43f Catch storage exception in scanner for remote shares
Whenever an exception occurs during scan of a remote share, the share is
checked for availability. If the storage is gone, it will be removed
automatically.

Also, getDirectoryContent() will now skip unavailable storages.
