Importing from legacy does not preserve the time of the notes

[Thalos12]

Current behavior

After importing from the old Boostnote, the creation times were reset.
All my notes now look like they were created at the same time, the time I imported them.

Expected behavior

All the notes should keep the creation times.

Steps to reproduce

1. Create a new File System storage
2. Go to the storage settings
3. Click on Import under Import Notes from Legacy BoostNote
4. Select a folder for the Legacy Storage and specify a destination folder
5. Click on Import
6. Check the times in the destination folder

Environment

Desktop

• Boost Note.next version: 0.9.0
• OS version and name: Ubuntu 18.04
