Scope values override Event values

[rhcarvalho]

Summary

In the Go SDK, setting certain fields on the scope override the equivalent fields in events, while in other SDKs the event fields take precedence.

Steps To Reproduce

Compare Scope.ApplyToEvent (Go) and Scope.applyToEvent (JS).

In particular:

Go

	if len(scope.contexts) > 0 {
		if event.Contexts == nil {
			event.Contexts = make(map[string]interface{})
		}


		for key, value := range scope.contexts {
			event.Contexts[key] = value
		}
	}

JavaScript

    if (this._contexts && Object.keys(this._contexts).length) {
      event.contexts = { ...this._contexts, ...event.contexts };
    }

Expected Behavior

SDKs should handle this type of detail consistently.

SDK

• sentry-go version: 0.9.0
• Go version: any
• Using Go Modules? [yes/no] either

Additional context

The spec is not clear about precedence, but seems that the JavaScript behavior is the one replicated elsewhere.
