ARQ-1458 Fixing the 'Could not inject members' issue

This bug was introduced by ARQ-1071 (https://issues.jboss.org/browse/ARQ-1071) in 1.0.4.Final and persists in current version (1.1.1.Final). The reason is that all ThreadLocal occurences were replaced by InheritableThreadLocal to fix a NPE on @Timeout usages.

This proposed fix consists on revert just one occurence of InheritableThreadLocal to ThreadLocal.
