#1 Equality of 2 ParamEntityWrapper instance return always false

[Yves Drumbonnet]

Equality on ParamEntityWrapper is always refused when bean id is stored in table of bytes (byte[]).
Suppose the id of a bean is a composite key, the way to marshall and unmarshall the id is to transform it in a table of byte.
But comparison of 2 tables of bytes is always false.

[Yves Drumbonnet]

Change org.adichatz.engine.common.Utilities.equals(Object, Object):
add test on equality of two tables of bytes.
