Bug 3134: (follow-up) improve ID and peport name sorting on saved reports page

The sort for ID is alpha instead of numerical, same for the report
names.

To test:
create id=1, name=Report 1
create id=2, name=Report 2
create id=10, name=Report 10
create id=11, name=Report 11

Sorting by id:
without this patch 1, 10, 11, 2
with this patch: 1, 2, 10, 11

Sorting by name:
without this patch: Report 1, Report 10, Report 11, Report 2
with this patch: Report 1, Report 2, Report 10, Report 11
