What is the current behavior?

As reported by @georgios-ts in the Qiskit slack, definitions of parameterized gates are being generated with an incomplete ParameterTable . Introduced by #4745 .

Steps to reproduce the problem

x = Parameter('x') 
rx = RXGate(x)
print(rx.params)
print(rx.definition.parameters)
>> [Parameter(x)]
>> set()

What is the expected behavior?
