[General] Throw when no gesture is passed to the GestureDetector (#3884)

## Description

Adds an explicit error message when `GestureDetector` is rendered
without any gesture. The current behavior is a random error when trying
to call a method on `undefined`.

## Test plan

Verify that the error is thrown when no gesture is passed.
