I refactor the test to use the FileLoader API rather than modify the host filesystem manually.

This is the check that would fail without the patch, returning a fd of -1.

Previously we were not clearing the
SharedFilesmap upon flush. As a consequence, when opening a shared file that had been (1) synced, and (2) flushed, the filesystem implementation would act as if the file was cached, and try to::openit.In more detail,
SharedFiles::syncSharedFilewould not sync back the file after flush.This PR fixes it and adds a regression test.
