Fix: File listing after update.

Issue: Updates to files were not stored in the GEDS internal cache.
This resulted in invalid file listings.

To mitigate this issue the following changes were added:
- Updates are now reflected in the cache.
- The metadata server is always queried when the file status is
  requested.
