Webspace manager uses request context params instead of request context service

[stollr]

Q	A
Sulu Version	2.5
PHP Version	doesn't matter
DB Version	doesn't matter
Browser Version	doesn't matter

Actual Behavior

The webspace manager, which is configured in the core bundle, relies on the request context container parameters router.request_context.host and router.request_context.scheme (see here) as fallback when no actual request object is available. This might happen during cache warming in a functional test.

But if the request context is configured by Symfony's framework.router.default_uri setting like it is described in their docs, the mentioned container parameters still uses the defaults (localhost and http). There is a issue which points this out symfony/symfony#53919.

In my case this leads to wrong url generation in a functional test (kernel test case) when the cache is warmed.

Expected Behavior

Sulu should use the request context values as fallback even if they are configured by the default_uri setting.

Possible Solutions

This can be fixed by using the request context service instead of the container params.
