Log plugins in ArtifactsManager are not compatible with detox.init(... launchApp: false ...) option.

[noomorph]

When the app does not get launched inside detox.init(...) call, then beforeAll hook in log plugins (ADBLogcatPlugin is affected and SimulatorLogPlugin might be too) has no actual opportunity to read app logs. This is completely reasonable since there is no app running to start with.

Users are getting exceptions like this:

Caught exception inside plugin (ADBLogcatPlugin) at phase onBeforeEach

This needs to be addressed by rewriting logic of abstract base class StartupAndTestRecordingPlugin and the implementations of SimulatorLogPlugin and ADBLogcatPlugin accordingly. They should mostly rely on onLaunchApp hook rather than onBeforeAll.
