Fix esim.saip.ProfileElementSequence.remove_naas_of_type

This method did not work at all at the moment, likely due to API churn
over time.  This change makes the following exception go away:

Traceback (most recent call last):

AttributeError: 'str' object has no attribute 'intlist'

A subsequent patch should introduce unit tests to avoid such breakage in
the future.
