Erik Johnston 360ba89c50 Don't fail requests to unbind 3pids for non supporting ID servers
Older identity servers may not support the unbind 3pid request, so we
shouldn't fail the requests if we received one of 400/404/501. The
request still fails if we receive e.g. 500 responses, allowing clients
to retry requests on transient identity server errors that otherwise do
support the API.

Fixes #3661
