Stop scanning files on close

MediaProviderWrapper.ScanFile has some weird side-effects, as we're not
sure when it inserts the file (even though it exists) and when it
updates the entry. This CL disables file scanning in close for now,
until we figure if and when we need files to be scanned.

Fix FuseDaemonTest accordingly.
