Tasks are called "Issues" in Activity Feed when Closed by Merge Request

Summary

Tasks (new Work Items) are labeled as "Issues" in the Activity Feed after being closed by a Merge Request.

Steps to reproduce

1. Create an Issue (i.e. Issue #1)
2. Create Tasks on the Issue (Tasks #2 and #3)
3. Create and merge an MR that closes one of the Tasks (i.e. "Closes #3")
4. Activity feed will show as "Closed issue #3"

Example Project

See https://gitlab.com/Rwarcards762/testing-of-tasks

What is the current bug behavior?

Create Issue with Tasks:

Showing ID of Task as proof:

Open an MR that will close a Task upon Merge:

MR even calls the task an Issue:

Once merged, the Task is closed, calling it an Issue:

Proof of it being closed:

What is the expected correct behavior?

Item should be called a "Task."
