Fix IAKERB accept_sec_context null pointer crash

When iakerb_gss_accept_sec_context() processes an initial token which
is not an IAKERB token (because the client already has a service
ticket), set *context_handle.  Otherwise subsequent GSS calls using
this context will dereference a null pointer and crash.

[ghudson at mit.edu: moved fix to cleanup handler to avoid code
duplication; added tests; rewrote commit message]
