Desktop: Fixes #11833: Restore notebook from trash without requiring selection

[rathoreSahil]

What this PR does?

• Resolves the issue where restore notebook does not work if the notebook is not selected first.
• Fixes Restore notebook from trash does not work if notebook not selected first #11833

Issue Description

• Open Joplin profile with multiple notebooks.
• Delete a notebook (move to trash).
• Right-click deleted notebook in trash. A context menu with "Restore notebook" appears.
• Click "Restore notebook". Nothing happens.

Root Cause

• The enable condition for restore notebook option was the 'folderIsDeleted' flag in the WhenClauseContext object.
  
  

• The stateToWhenClauseContext function is responsible for converting current state to WhenClauseContext object.
• It sets the context options for the current menu item based on the commandFolder which if not explicitly set is taken to be the currently selected entity by default.

• Since the currently selected item does not have 'folderIsDeleted' property set to true hence the restore notebook option is disabled.

Issue resolution

• We can pass WhenClauseContextOptions to the 'stateToWhenClauseContext' function through which we can explicitly specify the id of the command folder for the current menu item.
• The itemId of the currently clicked item was already being passes as an argument to the function which converts the command to a stateful menu item.
• I extracted the itemId and passed it as current commandFolderId option to the 'stateToWhenClauseContext' context function and this resolves the issue.

Problem

The issue was that earlier we were passing folderId as a raw string to the 'commandToStatefulMenuItem' function and i was extracting it from args and setting the WhenClauseContextOption, but the problem is that the itemId will not always be a folderId, it might also be a note id or a tag id hence the test case was failing where only a single note id was being passed to the function.

There are multiple ways to solve this:

• One way was to pass in a type along with the item id but that would lead to inconsistency in the code and might have led to changes in a lot a places just to maintain consistency.
• Another way is to pass in an object as { folderId: itemId } instead of plain itemId. We can then check whether the id is a folder id or not and set the context option accordingly else pass option as undefined which would lead to normal functionality.

Additional Changes

Also since the argument type changed I had to make a small change in the restoreFolder.ts file as well where i take an option object and extract folder Id from it.
