EditorManager: Add plugin tests for tabbed viewHEADmaster

Add tests for the specific behavior differences identified in the commit
introducing tabs 05bae4aca15a24ed46acf7928a18f0af953c69ec

- Suspending documents must keep tab open
- Moving an editor from one split to another should not close the
  original tab
- Closing the last tab of a split should not open another document in
  that split even if there are other documents open
- closing views (splits) should close documents if the only tab for
  it is closed, but not if there are other tabs for the documents, even
  if they are "suspended"
- If a tab with an editor is closed, we may not close the document
  if there is another tab for it, even a "suspended" one
- If a suspended tab for a document is closed that doesn't have any
  other tabs, the document must be closed
- when closing a tab and there are no other editors managed by the
  view (i.e. only suspended tabs), the view should change to a different
  tab, not any arbitrary document
