Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

Bug summary

This project by default uses a random UUID for every connection to the mqtt broker with cleanSession set to true which thinks it's a new device/connection and all the messages in the offline queue is dropped

Library version

0.3.2

Environment info

Running on Expo dev build on a real android device. Using Macbook for dev purposes

Steps to reproduce

1. Disconnect the mqtt connection
2. Reconnect ( automatically sets new clientID & cleansession to true)
