fix(uuid): update uuid.ts based on JS implementation

[visiodeibc]

Summary

Hi, this is Jake from the Technical Support team.

There was an issue of user properties being mapped incorrectly due to colliding UUIDs set by the Amplitude TS SDK[due to math.random function].

There was a fix in JS SDK but not carried over to TS SDK

• https://github.com/amplitude/Amplitude-JavaScript/blob/v8.x/src/uuid.js

The issue has been stale, so I am making PR for the issue!
