`Cannot read property 'uri' of undefined` when use jupyter interactive

Issue Type: Bug

Actual behavior

It will alert Cannot read property 'uri' of undefined when use jupyter interactive, and won't successfully activated. However, native jupyter works well.
I have tried reinstalling the extension and the vscode, but this problem still exists.

@ganxy1028 quick question. Do you currently not have a workspace folder open? Due to the error that I see in the console log I believe that we might not be handling this case correctly.

[IanMatthewHuff]

Actually a bit more info might be helpful as well.

1. How are you starting up the window? Just running a cell from that .py file that you have open?
2. What is the full path to the file that you have open?

My suspicion (you could try this out as a workaround) is that if you open up the folder that file is in as a workspace folder this will work.

[IanMatthewHuff]

Just for our team triage notes. It looks like it might be coming from here if the workspace folders had [undefined] which via the vscode api doesn't look possible.

public get rootPath(): string | undefined {
        return Array.isArray(workspace.workspaceFolders) ? workspace.workspaceFolders[0].uri.fsPath : undefined;
    }

Before it happen, there was a workspace folder D:\MyCareer\etiger\, then I just removed it from workspace. No workspace folder was opening up when I run the .py file to open a vscode, and run a cell from it. The full path is D:\Programs\Python\test.py

This morning, inspired by your reply, I tried to add D:\MyCareer\etiger\ workspace, and removed it, again, then this question just disappeared, everything all right. It seems that this issue can not be solved by reinstalling, rebooting, or updating to version 2020.4.74986 (20 April 2020), but re-remove workspace folder works.

Oh, there is still something wrong. With no folder in workspace, if I run any .py file to open a vscode, and run a cell from it, it might(about 50% chance) alert 'Cannot read property 'uri' of undefined and Unable to open 'Python Interactive':Cannot read property 'createKey' of undfined, and no Python Interactive will be open. If it successfully open a Python Interactive, everything seems OK, and then if I close the Python Interactive, and run a cell, this 'uri' & 'createKey' issue will 100% chance happen.
The whole Console that fail at the first cell-run(fail_1_log) and fail at the after close-Python-Interactive(fail_2_log) is attached.

I think it might not be an issue for this python extension, but for the vscode. This morning, I found a similar problem on Markdown All in One extension. I will go to vscode program to create an issue.

Sorry for my bother and thanks for your help.

Thanks for your work very much.
