Bugfix: Update metadata with new file_info before saving it the first time in the file

[MichaelOrlov]

This PR is a bug fix for missing file_info for newly created file in saved metadata.

When we are switching to new storage, the correct behavior shall be as follows:

1. Save metadata to storage
2. Close current storage
3. Open new storage for read_write
4. Update metadata with a newly created file
5. Save metadata to storage
