Retrieve Environment from RegisteredBean

[christophstrobl]

When loaded via aot factories EnvironmentAware is no considered. Therefore the processor uses the default StandardEnvironment which will miss out on potential application properties and others forcing users to work around the issue eg. by updating maven plugin configuration with

<systemPropertyVariables>
    <spring.aot.data.accessors.enabled>false</spring.aot.data.accessors.enabled>
</systemPropertyVariables>
