Data integrity crash

ReActiveAndroid Version: 1.4.3

Bug or Feature Request: Got a data integrity crash after updating data model and database version

Description:

java.lang.IllegalStateException: ReActiveAndroid cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number. You can simply fix this by increasing the version number.

I deleted a field from my model, and incremented the database version:

@Database(name = "propertyforce", version = 19)
public class AppDatabase {

It was 18 before. Here's how I'm initializing:

DatabaseConfig appDatabase = new DatabaseConfig.Builder(AppDatabase.class)
                        .addModelClasses(LogEntry.class, FarmReport.class, FarmReportProperty.class)
                        .disableMigrationsChecking() // Potentially destructive, so replace with migrations if adding any tables that need to persist
                        .addTypeSerializers(JsonSerializer.class)
                        .build();
                ReActiveAndroid.init(new ReActiveConfig.Builder(context)
                        .addDatabaseConfigs(appDatabase)
                        .build());

So I shouldn't need any migrations. Why is this happening?
