This bugfix makes sure that from a set of symbols with the same address, only the first one gets imported. After an assessment whether analysis scripts can deal with multiple symbols at the same address, an import of all symbols should be made possible in the future. This will also require to relax the primary-key constraint of the `symbols' table. Change-Id: I61c4ddb1af1556d44eab54e53eaa3d0fc20de7c1
