Crash reporter should use the specified temp folder

[feross]

• Electron version: 1.4.1
• Operating system: Windows

I set the Electron temp folder using:

app.setPath('temp', config.TEMP_PATH)

And later, I enable the crash reporter:

electron.crashReporter.start({
  companyName: config.APP_NAME,
  productName: config.APP_NAME,
  submitURL: config.CRASH_REPORT_URL
})

The crash reporter does not respect the temp folder setting. It creates the following file:

• %APPDATA%\Local\Temp\WebTorrent Crashes\operation_log.txt

(where %APPDATA% is the user's AppData folder, e.g. C:\Users\UserName\AppData)

This bug makes it impossible to make a Windows Portable App that is also "silent" -- i.e. doesn't leave any traces on the user's hard drive when the app is run from a USB stick, for example.
