    [BEAM-1908] Allow setting CREATE_NEVER when using a tablespec in BigQueryIO

    Currently, the BigQueryIO.Write transform doesn't allow CreateDisposition.CREATE_NEVER to be set when using a tablespec to determine the BigQuery table name dynamically at runtime.
    
    This check was originally put in because it was assumed that BigQueryIO would need to create a new table every time the tablespec returns a table name that hasn't been seen before. Since then a new BigQuery feature was released which enables date partitioning within a single table, and is now the preferred way to shard data by date (instead of having a table per date). It should therefore be possible to use tablespec to write to a specific partition e.g. `my-project:dataset.my_table$20170407`, while setting CreateDisposition.CREATE_NEVER since we never need to create a new table.
    
    This PR removes the check so that CreateDisposition.CREATE_NEVER can be used with a tablespec.
