Fixes::
Fixed a bunch of test cases for the task. We change workflow for tasks. we have added the projects child table and renamed the project to default project.

Expected Behaviour:

Running "before_tests" hooks
test_circular_reference (erpnext.projects.doctype.task.test_task.TestTask) ... ok
test_complete_task_with_assignment_closing (erpnext.projects.doctype.task.test_task.TestTask) ... ok
test_complete_task_without_assignment_closing (erpnext.projects.doctype.task.test_task.TestTask) ... ok
test_overdue (erpnext.projects.doctype.task.test_task.TestTask) ... ok
test_reschedule_dependent_task (erpnext.projects.doctype.task.test_task.TestTask) ... ok
