Fix SQLite error for table with "WITHOUT ROWID" & "STRICT"

Fixed issue that omitted the comma between multiple SQLite table extension
clauses, currently ``WITHOUT ROWID`` and ``STRICT``, when both options
:paramref:`.Table.sqlite_with_rowid` and  :paramref:`.Table.sqlite_strict`
were configured at their non-default settings at the same time.  Pull
