DeleteSourceAddress.seq - ASCONF chunk is received with Delete IP Address to delete an IP address that is also the source address
To check if ASCONF chunk is received to delete an IP address that is
also the source address of the ASCONF chunk, the receiver MUST send
an Error Cause TLV with the error cause set to the new error code
'Request to Delete Source IP Address'.

Association is established between endpoint A and B. Arrange ASCONF
in endpoint A such that ASCONF chunk with delete source address IP
address parameter is sent to endpoint B.

<----------------- ASCONF-ACK
(Delete Source IP Address Error)
TEST DESCRIPTION:
1. Send ASCONF chunk from endpoint A to B with delete delete an IP
address that is also the source address.
2. Check A: ASCONF-ACK with delete source IP address error should be
received at endpoint A.

5.3. General Rules for Address Manipulation
When building TLV parameters for the ASCONF Chunk that will add or
delete IP addresses, the following rules MUST be applied:
F8) If a request is received to delete an IP address that is also
the source address of the IP packet that contained the ASCONF
chunk, the receiver MUST reject this request. To reject the
request, the receiver MUST send an Error Cause TLV set to the
new error code 'Request to Delete Source IP Address' (unless
Rule F5 has also been violated, in which case the error code
'Request to Delete Last Remaining IP Address' is sent).
