A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

  Small fix after merge of fix for bug#16510

When setup_fields() function finds field named '*' it expands it to the list
of all table fields. It does so by checking that the first char of
field_name is '*', but it doesn't checks that the '* is the only char.
Due to this, when updating table with a field named like '*name', such field
is wrongly treated as '*' and expanded. This leads to making list of fields
to update being longer than list of the new values. Later, the fill_record() 
function crashes by dereferencing null when there is left fields to update,
but no more values.

Added check in the setup_fields() function which ensures that the field
expanding will be done only when '*' is the only char in the field name.
