reindexdb: Fix the index-level REINDEX with multiple jobs
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'.
