Fix error in %edit magic

[ccordoba12]

• The problem is the _find_edit_target method is a staticmethod in IPython.
• We have a test in Spyder for this magic, which detected that it's broken with 6.19.1.
• This regression was introduced in Add more tests #1034, according to git blame.

@ccordoba12, you can remove the edit magic test for now. The proper fix would be to use mock.patch, I thought what I had done was a proper work-around.

I made a simple fix for now, just to check that it's working. Should I remove that instead?

That sounds good, let's keep it in. Thank you!
