Comment(by burcin):
The conversions should be specified with the `conversions` argument to the
`BuiltinFunction` constructor. Having the conversion near the function
definition is easier to maintain than that table.
In this case, the constructor for
sage.functions.generalized.FunctionSignum should be changed to include
`'sympy': 'sign'` in the `conversions` argument.
