"Skip duplicates" doesn't work when adding to multiple accounts

[dlebech]

If the same transaction, with the same amount and same day appear on multiple accounts, "skip duplicates" will ignore it.

Potential solution: Use the account ID when determining the duplicate.

This kind of duplicate should happen so rarely that it might not be worth it to do this though. Instead, maybe just show number of rows skipped, so it's obvious to the user.
