Interactive Window does not work in saved workspace

[clayms]

Issue Type: Bug

I think I figured out the underlying cause of the following issues:

#7446
#7445
#7444
#7329
#7322

Interactive Window's do not work in saved workspace files.

When I start a new blank VS Code instance, and use Ctrl+Shift+P and select Jupyter: Specify local or remote Jupyter server for connections, specify my remote server url+token, then Ctrl+Shift+P and select Jupyter: Create Interactive Window, everything works as expected.

When I then do nothing else but save the workspace, everything breaks and I start running into all of the errors in the issues listed above.

@clayms If you don't mind I'm going to use this issue here as a bit of a meta issue for the problems here. I just checked the issues here and I do indeed repro them on current stable bits. However we just had a fix go in today here:
#7452
That fix unblocked #7448, #7450, #7446, and #7445 for me.

I'm going to dupe those issues against this issue here and keep this one open for verification. We plan on releasing a recovery build of the extension with this fix in it, so that should be coming out very shortly. #7444 looks different to me, so I've replied separate on that one, and I'm leaving it open.

Please reopen if this is not resolved in the August recovery release.
