* Fix misattribution of activity log entries to incorrect auth methods
In a production Vault Enterprise instance, I noticed incorrect
information in the sys/internal/counters/activity endpoints. Eventually,
I was able to spot a pattern of entities being misattributed to auth
methods of the same name in child namespaces, which led me to this bug
in the code.
When attempting to map from a token's path to an auth method, we need to
do so with respect to the namespace of the token, which may be different
from the namespace of the request, as tokens from parent namespaces can
make requests that reach into child namespaces.
