fix: remove init launch app

[chrisleewilcox]

Description

Our automated tests are launching the app multiple times at the start of the tests. To improve performance and stability of tests the tests should only launch the app once at the beginning of tests.

Didn't remove init.js because there is an error that occurs when running tests without init.js.
