Fix broken tests with a workaround to the deprecation of concat_alternatives in Gaudi v37r0
The two tests in this MR were broken by the removal of KeyValue concat_alternatives in the workarounds for Gaudi v37r0 (commit LHCb@4cb14f0e, part of LHCb!4355 (merged)) because the Rich RawEvent is not at the default location in the files used by these tests. This patch updates the options of the tests to look in the correct location
