Testnizer v1.4.10

Two follow-up fixes on top of v1.4.9 — the Home page now refreshes after
an import, and the folder Run action opens the run instead of the Tests
overview.

• Import: importing a project no longer requires an app restart to show
  up — the Home page project list refreshes immediately after the import
  completes.
• Runner: right-click Run on a folder now opens the run scoped to
  that folder's endpoints (the run config, ready to fire) instead of landing
  on the generic Tests overview.
