Fix 0003132: Email for feedback does not contain the last bugnote

M bug_update.php

• Change the update order to do the following:
  • Set the custom field values
  • Add the bug note
  • Update the bug

This makes sure that when the bug_update() api sends an email it contains the
new custom field values as well as the last added bugnote.
