Multiple annotations passed in am command not working as expected

### Description

If we pass multiple annotations in the am command, it runs all the tests instead of running only the tests with annotation.
Espresso documentation for multiple annotations - https://developer.android.com/reference/androidx/test/runner/AndroidJUnitRunner

### Steps to Reproduce

1. Add annotations to your test functions ( @Annotation1, @Annotation2 )
2. Run the am instrument command
3. ```adb shell am instrument -w -e annotation com.android.foo.Annotation1,com.android.foo.Annotation2 com.android.foo/androidx.test.runner.AndroidJUnitRunner```

### Expected Results

It should only run functions with the annotations. So if have 10 tests in total and we added annotation to only 2 , it should run **2/9** tests

### Actual Results

It runs all the tests in the testsuite

### AndroidX Test and Android OS Versions

com.android.foo/androidx.test.runner.AndroidJUnitRunner`
Android OS - 13

### Note

This works fine with single annotation param

```adb shell am instrument -w -e annotation com.android.foo.Annotation1 com.android.foo/androidx.test.runner.AndroidJUnitRunner```

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

Start at the AndroidJUnitRunner entry point and reproduce the issue with the supplied adb shell am instrument command using two annotations. Compare the single-annotation and multiple-annotation runs; done means the multiple-annotation command runs only tests carrying either specified annotation rather than the full suite.
