Task type: Bug Fix

Issue:
`activeEditorIsPinned` is not set when editor is auto-pinned by `workbench.action.moveEditorLeftInGroup`
Type: <b>Bug</b>

workbench.action.moveEditorLeftInGroup will automatically pin an editor if the editor to its left is pinned. When this happens activeEditorIsPinned is not updated and set to true. This context is only set when explicitly using workbench.action.pinEditor.

The reverse scenario has the same bug. Moving and editor to the right will unpin it if the editor to the right is unpinned. This will not set activeEditorIsPinned to false.
