fix: reset workspace before deleting a workspace (#23782)

## Description
Fixes [#12057](https://github.com/appsmithorg/appsmith/issues/12057)

In specific scenarios, the currentWorkspace is not up to date and uses a
previous workspace, which can cause certain API calls to fail. The end
result is the user sees a "No Resource Found" error with no clear
explanation.

This changes adds a new ReduxAction RESET_CURRENT_WORKSPACE with returns
it to it's initial value. The only place I've added that is at the
begining of deleteWorkspaceSaga()
