Methods quotient, quotient_module are not the same for some modules from sage.modules #34484
Description
The base class Module_free_ambient makes quotient and quotient_module the same, but some subclasses override only quotient.
sage: A = ZZ^3; V = A.span([[1,2,3], [4,5,6]])
sage: V.quotient
<bound method FreeModule_generic_pid.quotient of Free module of degree 3 and rank 2 over Integer Ring
Echelon basis matrix:
[1 2 3]
[0 3 6]>
sage: V.quotient_module
<bound method Module_free_ambient.quotient_module of Free module of degree 3 and rank 2 over Integer Ring
Echelon basis matrix:
[1 2 3]
[0 3 6]>
sage: A = QQ^3
sage: A.quotient
<bound method FreeModule_generic_field.quotient of Vector space of dimension 3 over Rational Field>
sage: A.quotient_module
<bound method Module_free_ambient.quotient_module of Vector space of dimension 3 over Rational Field>
