Java bingo-elastic substructure search cannot use QueryMolecule as target

**Steps to Reproduce**
```
var indigoObject = indigo.loadQueryMolecule(smiles);
var target = new IndigoRecordMolecule.IndigoRecordBuilder()
.withIndigoObject(indigoObject).build();
```

**Expected behavior**
We're expecting, that target will be loaded and used by SubstructureSearch

**Actual behavior**
```
