Handle reloading of REPL Window

[anthonykim1]

Resolves: #24021

[anthonykim1]

For the edge case:

create repl, reload repl, close tab, then open notebook, and then we fall into trap where we think notebook is repl.

I dont think we have to worry about this since I set the replUri and memento for native repl to undefined as I watch for notebook document closing. @amunger

one more step to test the edge case: create another repl and make sure it doesn't recover "into" the untitled notebook

[amunger]

to make it even more air tight, disable the python extension before reloading, and re-enable after creating the untitled notebook. That would simulate closing the tab before the python extension activated. At that point you would probably also need to check the label.

1. create repl
2. disable python extension
3. reload vs code
4. close the repl tab
5. create new notebook
6. enable python extension
7. create python repl

Progress notes:

Testing this DOES seem like repl almost steals the new untitled notebook.
Trying to solve this by finding fileName or tab name but both untitled notebook and Python REPL show up as 'Untitled-ipynb' :/

I think the only place Python extension does anything with tab name is:

vscode-python/src/client/repl/replCommandHandler.ts

Line 36 in 29d4f35

asRepl: 'Python REPL',

when we call showNotebookDocument and pass 'Python REPL' as asRepl here

export interface NotebookDocumentShowOptions {
		/**
		 * The notebook should be opened in a REPL editor,
		 * where the last cell of the notebook is an input box and the other cells are the read-only history.
		 * When the value is a string, it will be used as the label for the editor tab.
		 */
		readonly asRepl?: boolean | string | {

Could this is bug in the NotebookDocumentShowOptions or showNotebook document where tab name somehow gets lost? @amunger

[amunger]

the label property on the tab object should work
