Fix time translations in course people page
Fix time translations in course people page

fixes VICE-2095
flag=none

Test Plan:
 - ensure I18n plugin is enabled with custom Spanish translations
 - go to course settings
 - change language to a custom Spanish setting
      Example: Español (Chile)
 - go to the course people page
 > last activity should have the format “{date} en {time}”

Note:
I am having a hard time reproducing in my local dev environment.
I am getting a result that is similar when setting my language to
non-custom Espanol. We will need to verify that this works on CD
to be sure.
