Fix closing details view when viewing file in folder

The Files app active view is set to "files" in silent mode to avoid an
unneeded load of the "/" directory. However, this also prevents the
details view from being automatically closed, so it has to be explicitly
closed by the Goto plugin; the approach used is the same that would have
been used by OCA.Files.App._onNavigationChanged if not silenced.

Fixes #1448
