Fixed creating chunk for field in wrapper with package-private type

[Damtev]

Description

Field threadLocals in java.lang.Thread has package-private type ThreadLocal.ThreadLocalMap, so in the corresponding wrapper this field has type Object. But Hierarchy searches a field by subsignature, what is not applicable in such case. So, we need to search only by name.
