Environment details

1. BigQuery API
2. OS type and version: MacOS 10.15.5
3. Java version: 13.0.2
4. bigquery version(s): group: 'com.google.cloud', name: 'google-cloud-bigquery', version: '1.116.10'

Steps to reproduce

1. Create query:
   DECLARE ids_filter ARRAY default ["1"];
   SELECT TO_JSON_STRING(query)
   from (
   select * from TABLE
   WHERE row.id IN UNNEST(ids_filter)
   ) as query

2. results = job.getQueryResults( --> throws NullPointerException
   BigQuery.QueryResultsOption.pageSize(10),
   BigQuery.QueryResultsOption.startIndex(0);
   );

Stack trace

java.lang.NullPointerException	at com.google.cloud.bigquery.BigQueryImpl.listTableData(BigQueryImpl.java:1021)	at com.google.cloud.bigquery.BigQueryImpl.listTableData(BigQueryImpl.java:1010)	at com.google.cloud.bigquery.Job.getQueryResults(Job.java:312) ............. 

Any additional information below

Due to DECLARE statement and before the following reload, the destination table is null.
Once the job is reloaded it does not override current (this) job

Job job = this; if (job.getStatus() == null || !JobStatus.State.DONE.equals(job.getStatus().getState())) { job = reload(); } 

 TableId table = ((QueryJobConfiguration) getConfiguration()).getDestinationTable(); 

and cause the crash later in listTableData while accessing tableId.getProject().

When DECLARE statement omitted, the query works OK, also, the response has relevant information responded by BigQuery.
In both cases, the destination table is not overridden but without DECLARE it is not null.
