🐛 — Fix timezone mess
I had one operation which date was at midnight, but with a +0200 timezone. The looking for similar operations was made with this date but in GMT time, two hours before, so Kresus was looking in the previous day. The result was that the last operation was always duplicated, each day I had to merge it.
With this commit, I remove the change of timezone in the dates used for looking for similar operations.
