Importing issue within AddressManager

Hello,

While importing from a vcard file, I noted the Birthday dates were 
modified as (day - 1). My vcard was previously converted from the 
Birthday (old bsd cli program) format and it had no errors, while 
birthday dates were badly imported in AddressManager.

As you might know, this data is used within SimpleAgenda to fetch 
Birthdays, so we need a correct importing process.

Below, a screenshot with the vcard imported and the rendered date in 
AddressManager:

Regards,
Patrick
