Description
When delete a pending document, the workflow task may not be deleted. This can result in having content being approved even though it's deleted content.

Steps to reproduce

1. Setup DXP
2. Start Liferay and login as default user([e-mail])
3. Goto "Content > Document and Media"
4. Create a folder and set "Single approver" workflow to it
5. Navigate to the folder created by step 4
6. Add a document and "Submit for Publication"
7. Goto "My Workflow Tasks > Assigned to My Roles" and confirm that there is a workflow task
8. Goto "Content > Document and Media" and delete the document
9. Goto "My Workflow Tasks > Assigned to My Roles" and confirm that there is no workflow task
10. Repeat the steps 6 and 7
11. Goto "My Workflow Tasks > Assigned to My Roles" and select "Assign to Me" for the task.
12. Approve the task
13. Goto "Content > Document and Media" and edit the document, "Submit for Publication" (the document version will be 1.1, status:pending)
14. Goto "My Workflow Tasks > Assigned to My Roles" and confirm that there is a workflow task
15. Move the document to recycle bin
16. Goto "My Workflow Tasks > Assigned to My Roles" again

Actual result
The workflow task exist and is possible to approve/reject (with inconsistent results)

Expected result
The workflow task will be deleted Automatically as in step 8~9.
