* Minor changes

* Remove console.* logger plugin

... as it doesn't work in Electron

* Only open/close panel editor options and groups when state is inverted

... meaning, only open when closed and only close when open. This avoids unpredictable states, causing inconsistent results.

* Support for adding multiple datasources and dashboards

... and having them all auto-removed when tests are completed

* Avoid page errors when removing dashboards and datasources [keep?]

* Wait for chart data before saving panel

... so that everything is ready when returning to the dashboard
