Fix Test fail with variable length memory address

The unit test class PIPConfigurationTest.java has a test that checks a
configuration string for length. However, the length of the "piptype"
field in that string can vary, causing the test to intermittently fail.

Field that passes:
piptype=org.onap.policy.rest.jpa.PIPType@71b3bc45

Field that fails:
piptype=org.onap.policy.rest.jpa.PIPType@a8c1f44

This fix removes the memory address from the "piptype" field, so that the configuration string will
now always be 323 characters in length.
