Open the last opened workspace/directory when there is no folder/workspace query param

Open the last opened workspace/directory when there is no folder/workspace query param (unless the ignore-last-opened flag is set)

Introduced in #4414

@code-asher may have more details.

To test:

1. Open a directory or workspace
2. Remove the ?folder or ?workspace query param and reload
3. Observe the last directory/workspace you opened is no longer open

I believe this is no longer possible since upstream moved this state from the server to a to a client side SQL database.

The way we did this before was to read our settings file and set it in the workbench web configuration which takes a URIs for the folder and workspace to open.
