CAL-940 [Quick Creation menu] Missing new user calendar name in the notification when add new event/task

Problem analysis:
* A user can have other user calendar rather than the default one. There is no need to restrict user calendar only to the default one.

Fix description:
* Get the name of the selected user calendar, either the default or a new user calendar.
