IntentsTestRule does not capture immediate intents

### Description

When using IntentTestRule, Intents that get started immediately (for example from `onCreate` method of the tested activity) do not get matched.

### Steps to Reproduce

1. Create an activity that starts another activity in its `onCreate` method
2. Create test for that activity using `IntentsTestRule` that attempts to match start intent
3. Test will fail -

### Expected Results

Start of another activity should be recorded

### Actual Results

Intents will not detect any intents (error message will print out `Recorded intents:[]`)

### AndroidX Test and Android OS Versions

`espresso-intents` 3.1.1
`Android` 9

### Workaround

Workaround to the issue is simple: Create a copy of `IntentsTestRule` and initialize intents in `beforeActivityLaunched` instead of in `afterActivityLaunched`

Lies zunächst IntentsTestRule und vergleiche, wann Intents in beforeActivityLaunched gegenüber afterActivityLaunched initialisiert werden. Reproduziere eine Activity, die aus onCreate eine weitere Activity startet, mit espresso-intents 3.1.1, und überprüfe anschließend, dass der Start aufgezeichnet wird, anstatt Recorded intents:[] zu erzeugen.
