QSqlTableModel/QSqlQueryModel and insertColumns problem.

After inserting a column, fetching data through QSqlTableModel was
off by one or more, since it passed the indexInQuery through to
QSQM.  Also, the headerData would sometimes return a blank string
for an inserted column, and sometimes the column number.

The autotests have been beefed up a little to check insertRows and
insertColumns play nicely.
