To get rid of implicit filters related workarounds in future let's
deprecate them now.
Deprecation warning breaks some bash iotests output, so fix it here
too: in most of cases just add filter-node-name in test.
In 161 add FIXME and deprecation warning into 161.out.
In 249, the test case is changed, as we don't need to test "default"
filter node name anymore.
