text: Title: PauliString.after() crashes for Clifford gate PhXZ(a=0.25,x=-1,z=0) in _decompose_into_cliffords 
  Body: **Description of the issue**
  
  PauliString.after() should be able to return a PauliString with Clifford ops input, but failed for the Clifford gate `PhasedXZGate(axis_phase_exponent=0.25, x_exponent=-1,z_exponent=0)`.
  
  **How to reproduce the issue**
  
  ```
  >>> a = cirq.NamedQubit('a')
  >>> ps = cirq.PauliString() * cirq.Y(a)
  >>> phxz = cirq.PhasedXZGate(axis_phase_exponent=0.25, x_exponent=-1,z_exponent=0)
  >>> ps.after(phxz.on(a))
