[PULL 08/26] tests/qtest/migration: Add negative tests to validate migration QAPIs

[Peter Xu <peterx@redhat.com>]

From: Het Gala <het.gala@nutanix.com>

Migration QAPI arguments - uri and channels are mutually exhaustive.
Add negative validation tests, one with both arguments present and
one with none present.
