fix(electron): Do not sync to NativeClient when autoDetectErrors or nativeCrashes are disabled

[yousif-bugsnag]

Goal

If either of enabledErrorTypes.nativeCrashes or autoDetectErrors are disabled, we don't install the sync layer (NativeClient.install) but still call all the methods to sync state to the native client.

Currently this logs an error message: Sync layer is not installed, first call install(), which isn't very useful as users can't call NativeClient.install

This PR updates each of the plugins that sync to the native layer to ensure that they do not sync to the native layer if those config options are disabled. This affects:

• plugin-electron-client-state-persistence
• plugin-electron-app
• plugin-electron-device
• plugin-electron-session

Testing

Added unit tests to assert that the native sync methods are not called when the relevant config options are disabled.

Also updated the makeClientForPlugin function in electron-test-helpers to support creating a client with an array of plugins - this allows the client-state-persistence unit tests to make use of the test helper since the plugin depends on the client-state-manager plugin being loaded.

I think it might be safer to check for enabledErrorTypes.nativeCrashes before trying to sync to the native client rather than removing this error

couple of small comments, but approved based on unit tests as I don't understand enough about Session.prototype._track or client._sessionDelegate and why you would use one over the other.

Session.prototype._track just updates the handled/unhandled event count for the session, whereas client._sessionDelegate is responsible for starting/pausing/resuming sessions
