Assignment - support multilanguage group names on 'view all submissions page'

Hi,

While testing MOBILE-4288 we saw that on browser multilanguage group names are not correctly displayed in some cases in assignment.

Assignment: teacher still see the multilanguage group names wrong. It shows all the names without the multilang, so "<span class="multilang" lang="de">Abgabegruppe</span> <span class="multilang" lang="en">Submission group</span> A" in any language is displayed as Abgabegruppe Submission A" (when in English it should have been Submission A and in Deutsch Abgabegruppe A)

I think this was already happening on MDL-74606, one of the screenshots there show:

I think this might had partially corrected elsewhere. I see (4.3dev which right now is a 4.2) it correctly when grading but I don't see it correctly on the view all submissions page:

(This test is slightly different ans we used as a group name <span class="multilang" lang="es">Grupo</span><span class="multilang" lang="de">Abgabegruppe</span> <span class="multilang" lang="en">Submission group</span> A that is the reason that on the second screenshot the naming is different)

Reproduction steps for assignment:
In a course in which you possess teacher privileges:

1. Create groups with names containing multilanguage strings, e.g. "<span class="multilang" lang="es">Grupo</span><span class="multilang" lang="de">Abgabegruppe</span> <span class="multilang" lang="en">Submission group</span> A"
2. Be sure at least one of the students is on that group
3. Add an assignment activity and configure it as follows:
   • 'Students submit in groups' to yes
4. As a teacher access that assignment, and click on 'View all submissions'. See that the name of the group is wrong

Thanks for your time,
Isabel
