If the blockchain analyzer encounters a cancellation transaction with foreign inputs - a technical impossibility but a logical possibility - or foreign outputs, then set its input anonsets to 0.

It may not comprehensively fix all the problems noted in #11226. However, it improves and closes #11226

After this PR, a new issue may be opened if there are still any problems.

This doesn't fix #11226:
I cannot reproduce Issue 1 but I doubt that this PR fixed it because I couldn't do that even with master yesterday.
I can reproduce Issue 2.

Note that in #11226 all inputs and outputs are ours.

While testing this I got a cancellation tx that was confirmed but it had no icon and no labels. I am not sure it is related to this PR:

I'm the Buddha. I have no wants. But sure, add it.

Nice trick, but I see through you Buddha attack type. I am Buddha as well and wait until you create the PR or let it go. AUMMMM

At last, your third eye bested mine. Then let's practice mindfulness and let it go. AUMMM
