fix: handle situation where GitLab does not return valuesjlvillal/pagination

If a query returns more than 10,000 records than the following values
are NOT returned:
  x.total_pages
  x.total

Modify the code to allow no value to be set for these values. If there
is not a value returned the functions will now return None.

Update unit test so no longer `xfail`
