Shared preferences folder not consistent across tests

[guillaume-tgl]

Description

Within the same test class, the shared preferences folder is not always present depending on the different tests within that class.

Steps to Reproduce

@RunWith(RobolectricTestRunner::class)
class SharedPrefsTest {

    @Test
    fun testSharedPrefsFolder() {
        val context: Context = ApplicationProvider.getApplicationContext()
        Assert.assertTrue(File(context.applicationInfo.dataDir, "shared_prefs").exists())
    }

    @Test
    fun testSharedPrefsFolder2() {
        val context: Context = ApplicationProvider.getApplicationContext()
        Assert.assertTrue(File(context.applicationInfo.dataDir, "shared_prefs").exists())
    }
}
