#4208: implemented getBeanClass in SupplierBeanBridge (see below)

The method JersetBean.getBeanClass is used to compute the bean
identifier. The default id for a JerseyBean<T> is
"java.lang.Object#jersey", causing collisions of bridge instances.

In particular, for HelloWorldResourceTest, Weld's MapBeanStore returned
a SupplierInstanceBeanBridge instead of the expected SupplierBeanBridge,
because both shared the same bean identifier.
