[BUGFIX] Provide minimal serverParams for Frontend functional subrequest (#<I>)

Provide minimal serverParams array for core <I> compatible frontend

subrequest, so the normalized param attributes are set through

corresponding frontend middleware, which is needed for some

functional tests, ex. PageTypeSuffixDecorator tests.
