Fatal Exception: java.lang.InternalError

In my application, I use Firebase Crashlytics, and it sent me a notification that hundreds of users are experiencing similar errors, which it has identified as 'crashes'.

## Expected Behavior
No crashes

## Current Behavior
Intermittent crashes on user devices reported by firebase crashlytics

## Possible Solution
add `catch (InternalError e)` at [AmplitudeClient.java:2383](https://github.com/amplitude/Amplitude-Android/blob/34c94580491b99a63df99e854db369de9217e167/src/main/java/com/amplitude/api/AmplitudeClient.java#L2383)
