[IMP] project: set default analytic account and analytic tags in task

Currently, the project's analytic account and analytic tags are not set by
default in the task.

Technical-
- In this task, we have added a demo of analytic tags in the project.
- The default_get() method does not call when the demo data is loaded, so
  the analytic account and analytic tags are not set. So we called
  default_get() from _load_records_create().
