…bug:config and consistently resolve parameter values (herndlm)This PR was merged into the 4.4 branch.Discussion----------[FrameworkBundle] Fall back to default configuration in debug:config and consistently resolve parameter values| Q             | A| ------------- | ---| Branch?       | 4.4| Bug fix?      | yes| New feature?  | no| Deprecations? | no| Tickets       |Fix#41121| License       | MIT| Doc PR        | n/aBrings back determining the default configuration from pull request#30648. Refactors determining the extension config into a helper method to keep cognitive load low with early exits instead of nested ifs.Additionaly, while reviewing, we noticed that entries with parameters are not resolved correctly if they come from the default config and an application config is existing but they are not overriden. E.g. the session config for the framework would output `save_path: %kernel.cache_dir%/sessions` instead of the resolved value.Tested via unit test (obviously) and by manually removing bundle configuration in a Symfony project.Beware that I do not know much about bundles and internals, I looked that up while implementing this and might have missed better/simpler solutions or edge cases. Please somebody also do another functional test to ensure this is really working as it should.Commits-------9b6110b [FrameworkBundle] Fall back to default configuration in debug:config and consistently resolve parameter values
