fix correct AMS header selection
...
When we are verifying the ARC seal we need to fetch the raw AMS header
from the header list. But it's not enough to return the first one we
find, since we may be interested in a different arc seal, we need
to search for the correct ARC index.

Don't log message content by default.
...
Right now, it is quite easy to end up logging the whole message in the
log when verifying signatures. This can result in wasted resources
writing the log to disk and increasing memory usage. This can also be
a private data leak if logging is put in DEBUG in a production
environment.
