[TASK] Disable functional tests

Extbase ships with a functional test class "FileContextTest" which
contains 10 tests. All those test fail currently.

The core does not (yet) have a strategy for functional tests.
As an intermediate solution, disable the functional tests.

They can be reactivated later if the core found a general concept for
functional tests.

AdditionalWhereClause pid statement for set rootLevel=-1 will be empty,
and for rootLevel = 1 it will limit the query to pid = 0.
For not set rootLevel or rootLevel = 0 the given Pids are taken into
account.
