Speed up Redux dev tools by disabling log serialization

Summary: Serializing the logs of the devices within Redux dev tools was causing Electron to crash due to it being out of memory. We can sanitize the state serialization by rewriting the device logs to <<DEVICE_LOGS>>. This fixes the issue and causes Electron to use less memory and CPU while in devlopment mode.
