[SR-Users] use append_hf() and remove_hf() on the same message

I'm using remove_hf() and append_hf() to manipulate the sip headers
on my application. Apparently, calling insert_hf("foo") after
remove_hf("bar") if bar is the last header (not including
Content-Length) is a bad idea, foo doesn't get inserted (I understand
that the append_hf() command tries to insert foo after bar, and since
bar just disappeared, well, it fails)

What is the safest way to both remove and append headers on the same
