[Fix] mail: incorrect activity creation date

After an activity creation, if a user checks the activity's information,
the creation date will be the current date.

To reproduce the error:
1. Add an activity (e.g. a TODO activity)
2. In log notes, click on the activity's information icon

=> The "Created" field is actually the current date and not the
activity's creation date.
