utils: Pass GcalCalendar to ask_recurrence_modification_type()

The method ask_recurrence_modification_type() currently
receives an ESource, and tried to fetch the ECalClient
from the ESource by using g_object_get_data().

However, since we moved to GcalCalendar, we do not set
this data field in ESource.

Receive a GcalCalendar instead, and use the appropriate
function gcal_calendar_get_client() instead.
