Go to does not work with __getattr__

[Morikko]

Description

I have a class B that wraps another one A through composition. I have setup __getattr__ to transfer everything from B to A.

The completion is working but when I want to Go to on b.toto, I have no definition found.

The completions were probably added there: #997

Code

import jedi


code = """
class A:
    def toto(self, a: int):
        ...


class B:
    _a: A

    def __getattr__(self, name):
        return getattr(self._a, name)


b = B()

b.toto(a="1")
"""

jedi_script = jedi.Script(code=code)

jedi_script.goto(line=16, column=1, follow_imports=True)
# [<Name full_name='__main__.b', description='b = B()'>]

jedi_script.complete(line=16, column=4)
# [<Completion: toto>]

jedi_script.goto(line=16, column=4, follow_imports=True)
# []

Expected

I would expect that the function goto returns [<Name full_name='__main__.A.toto', description='def toto'>] like if I would apply it on a.toto.

Actual

It returns an empty array.
