fix(core): prevent uncaught promise rejection

[simeng-li]

Summary

Globally catch unhandled promise rejections and log them to Application Insights.

The unhandled promise rejection was first observed in the TenantPool class's get method. If the tenantId is not found, the getTenantDatabaseDsn method will throw a tenant not found error. We use a try-catch block to catch the error and throw it with logging. However, if the Tenant.create Promise is read from the cache, somehow the error is not caught.
An unhandled promise rejection is thrown, which will crash the app.

The root cause of this error is still unknown. To prevent our production app from frequently crashing, we add this global catch instead.
