Race Condition leading to logging errors

In certain setups with threaded web servers, Audited’s use of
Thread.current can incorrectly attributed audits to the wrong user.

Fixed in 5.3.3.

In March, @convisoappsec noticed that the library in question had a
Race Condition problem, which caused logs to be registered at times
with different users than those who performed the genuine actions.
