Display change number instead of change id

Displaying the full patchset id in title of jobs screen is ugly,
use the change number and patchset number instead.

Previously it was:
  "Report for change myproject~master~I08ef433d6e141247ef72e30ee2143eb6a52ca14c,1"

After this change:
  "Report History for Change 5/1"
