Dividend transfers are duplicated

[oasuncion]

If an equity trade which pays dividends is copied, dividends transfers are duplicated.

To Reproduce Steps to reproduce the behavior:

1. Go to the Equity transfer window
2. Load an equity trade which pays dividends, and copy it
3. Go to the transfer window and load dividends transfers for this equity: dividend transfers have been duplicated

Expected behavior If a trade is copied, the dividend transfers should not be duplicated. More generally, when booking an equity trade, if a dividend transfer is already created for given product, currency, book, settlement date, it should not be duplicated.
