Character rename and addon reset

So I changed one of my characters name today and after login in got very surprised to see all my addons configuration reset to default. Was hoping maybe there will be some old files remaining in the WoW/WTF/Account directory, but it looks like the directory with old name got deleted...
Is there maybe something I'm missing? Some way to restore the configuration?
Setting it all up from scratch will take a lot of time, I'm really disappointed there was no warning to do a backup on the character rename screen.

Most of the addons have profile section where you can copy your old config from your old name to your new name.
Examples are Recount, Bartender, Omen etc..
