Deprecation messages not shown

[PabloKowalczyk]

Crunz version: 1.10.0

PHP version: 5.6

Operating system type and version: Alpine linux 3.8

Description
Deprecations triggered in \Crunz\Configuration\ConfigurationParser (probably in other classes too) are not handled by handler registered in \Crunz\Application::registerDeprecationHandler.

How to reproduce

Trigger deprecation in \Crunz\Configuration\ConfigurationParser::parseConfig method:

@\trigger_error("Test deprecation", E_USER_DEPRECATED);

Possible Solution

Try to call registerDeprecationHandler earlier, ideally just after container initialization.
