I don't think they "forgot"; I think they deliberately decided against retconning it to stay accurate to how it was in XY.There was no gender differences in Gen6 for eevee and I was sure Serena's Eevee was female. Now, female eevee tails must have heart-shaped white fur. It seems they forgot fixing Eevee's tail in flashback scenes.
Though I'll admit it's weird that they care about that now when there's precedence for updating designs in flashbacks as early as DP (Ash's Caterpie's mouth being changed from yellow to green).
