Tests failing with StackOverflowError cause a secondary OOM in TestExecutor

### Description

### Steps to Reproduce

```java
@Test
public void testWithInfiniteRecursion() {
recurseInfinitely();
}
```

### Expected Results

Test runner reports the StackOverflowError.

### Actual Results

Test runner crashes, because it tries to write the entire stacktrace to the summary writer:

```
Test failed to run to completion. Reason: 'Instrumentation run failed due to 'Process crashed.''. Check device logcat for details
Crash Message:Failed to allocate a 8994568 byte allocation with 462080 free bytes and 451KB until OOM, target footprint 201326592, growth limit 201326592

### AndroidX Test and Android OS Versions

AndroidX Test Runner: 1.1.2-alpha01

### Link to a public git repo demonstrating the problem:

Riproduci il malfunzionamento con l'esempio fornito testWithInfiniteRecursion, quindi ispeziona androidx.test.internal.runner.TestExecutor in TestExecutor.java:68, dove lo stacktrace viene scritto nel summary writer. Il lavoro è completato quando il test runner segnala StackOverflowError senza andare in crash con un OutOfMemoryError secondario.
