fix: handle redis client error events

[dnechay]

📚 Context/Description Behind The Change

Under the hood this package creates its own instance of redis client to subscribe on redis events. This client is an instance of EventEmitter and in case of errors it emits error event. When this event doesn't have at least one subscriber - Node.js process is crashed.

When using this library in some production service, it leads to uncontrolled crashes (no way to handled it via process.on listeners), so we have to add such listener here

🚨 Potential Risks & What To Monitor After Deployment

Don't see any

🧑‍🔬 How Has This Been Tested?

• adding the same code directly on installed package and shutting down redis instance, verify service not crashed

🚚 Release Plan

Merge, get new version, bump everywhere in MM
