Use last_selected_directory() when invalid path is passed to CrOS file picker.

Use last_selected_directory() when invalid path is passed to CrOS file picker.

This is for working around the case when <input type="file"/> control is used
twice; CrOS file picker kindly resolves a remote file path to a local cache
and the type=file control tries to default to the path, but the cache path
itself is out of user-visible directory. In such a case, we just use the
last_selected_directory(), rather than going back to the very default directory.

Could you take a look?

+hashimoto: who knows well about Drive path resolution.

Does this impact windows at all?

No, it doesn't. Extension-based file picker is used only for Chrome OS.
(important logic like file_manager_util is located under chromeos/ directory).
