Files.app: Use createDirectoryContents_ method during search.

Files.app: Use createDirectoryContents_ method during search.

Previously, during typing a search query on the drive, Files.app uses
DirectoryContents#createForDirectory method. It does not handle FakeEntries so
it causes an exception if a user typing a search query in the drive special
folders. This CL replace the method with createDirectoryContents_, which is
a caller of the createForDirectory method and can handle FakeEntries.
