why:
* tweaking previous commit g/287726 to properly show the new icon based
on the FF
refs EVAL-2304, INTEROP-7308
flag=updated_mastery_connect_icon
test plan:
* with an LTI tool installed in a course and an
unpublished assignment of external_tool submission type
in that course
* enable the updated_mastery_connect_icon FF for site_admin
* in a rails console, make this assignment seem like it's for Mastery
Connect:
```
assignment.external_tool_tag.update!(external_data: {
"key"=>"https://canvas.instructure.com/lti/mastery_connect_assessment",
"objectives" => "6.RP.A.1"
})
```
* in the assignment index, this assignment should use the unpublished
MC icon (dark grey)
* in the modules index, add this assignment to a module. it should use
the unpublished MC icon
* publish the assignment
* in the assignment index, it should use the published MC icon (green)
* in the module index, publish it if needed - it should use the
published MC icon (green)
