### Issue Details

* **Electron Version:**
  * All up to and including `9-x-y`
* **Operating System:**
  * Linux
* **Last Known Working Electron version:**
  * Never 😢 

### Expected Behavior

When a crash occurs the `crashReporter` module should send the crash dump to your reporting URL along with some extra metadata including a `guid` attribute that is a UUID for the user sending the crash to you.

### Actual Behavior
No `guid` 😢
