Check Hooks in AsyncServiceProvider must throw exceptions

[Lafunamor]

Problem

When verifying input in async service providers using the predefined methods (e.g. beforeUpdate) Exceptions must be thrown to stop the flow.
This is not optimal and should be revised.

Requirements

• no exceptions should be used for flow control

Proposal

• Refactor AsyncServiceProvider to use other methods than exceptions for flow control. E.g. the methods could return Boolean values.
