- Use `path` module from browser process in sandboxed renderer. This is required because the return value of `path.join` is platform-specific, and this is an assumtion of crash-reporter.js which is shared between sandboxed and non-sandboxed renderers. - Set `process.platform` and `process.execPath` in sandboxed renderer environment. This is required to spawn the windows crash service from sandboxed renderer. - Use a single temporary directory for all crashReporter tests. This is required to make tests more deterministic across platforms(since mac's crashpad doesn't support changing the crash dump directory). Also make a few improvements/fixes to the `uploadToServer` test.
