B only entries are imported to A as "expired"

[fallmake]

I successfully used the application today to sort out and merge multiple versions of the same database acrued over time (manual backup files/copies, automatically created backups from tools and extra copies from file sync issues). Thank you for the effort, it was very helpful. I noticed the following behavior:

1. Open 2 databases with only B containing a specific entry without expiry (i.e. normal, "active" entry)
2. Import said entry to A
3. Save A
4. Open A in KeePassXC

The imported entry shows as expired, with the original creation date from B set as expiration date. It shouldn't have expiration set (unless that was a property of the entry in B)
