Remove asserts from integration test

The integration for rft is not setup to properly run with ert. The
single realisation will cause ert to fail with "no ensemble variation".
Ert used to continue with the second iteration, but now stops (as it
should). We only make sure that we do not get any errors when GEN_DATA
tries to load the file (e.g. syntax error in input, incorrect filename
etc).
