47f99a407d introduced a parallel index-level REINDEX. The code was written assuming that running run_reindex_command() with 'async == true' can schedule a number of queries for a connection. That's not true, and the second query sent using run_reindex_command() will wait for the completion of the previous one. This commit fixes that by putting REINDEX commands for the same table into a single query. Also, this commit removes the 'async' argument from run_reindex_command(), as only its call always passes 'async == true'.
