Fix KAddressBook crash when editing a contact with nonstandard phone type
In this case PhoneComboBoxType::setType() attempts to insert the new type as the penultimate item in the mTypeList. However, using an iterator for insertion appears to cause an assertion within QList. There is no need to obtain an interator to do the insertion, the index can be used directly.
Test case: Importing this contact into KAddressBook and attempting to edit it will trigger the crash.
