v2.2.2 - fix flaky tests, fix UnboundLocalError in MainWindow.createNewProject (#94)

* search more than one filename for compName

* remove extra QVBoxLayout

* insert default components using name instead of index

* bump version 2.2.1 to 2.2.2

* tests do not use `.config` for settings
Core.storeSettings() is no longer called as a side effect any time avp.core is imported. Thus the tests use a new `initCore` method and the normal user path now relies on entering via `cli.py`. This means certain toolkit functions (e.g., ones using `FFMPEG_BIN`) no longer work if imported from a different python script, unless they call Core.storeSettings() themselves to initialize the settings.ini file

* fix UnboundLocalError in createNewProject
