Record ID match fails inside OR for legacy string keys.

[matre]

If a database with IDs stored as strings is opened in version 4.3.2, old records can still be retrieved by ID using a "_id" on top level. However, if the "_id" filter is placed inside an OR (or AND) clause, no document will be returned for documents with string ID. The behavior can be reproduced by storing "_id" as string in a new file database.

Test "ID String search" passes while "OR ID search" fails.

	private static Nitrite open(File file) {
		NitriteBuilder builder = Nitrite.builder();
		MVStoreModuleBuilder mvBuilder = MVStoreModule.withConfig().compress(true);
		mvBuilder.filePath(file);
		builder.loadModule(mvBuilder.build());
		return builder.openOrCreate();
	}

	private void buildDb(File dbFile, Object...docIds) {
		
		try (Nitrite dst = open(dbFile)) {
			
			NitriteCollection to = dst.getCollection("my_table");
			
			for (Object docId : docIds) {
				Document copy = Document.createDocument();
				
				copy.put("_id", docId);
				to.insert(copy);
			}			
			dst.commit();
		}		
	}
