msi: avoid negative index in TABLE_insert_row

[Aric Stewart]

What appears to be happening is There is an existing table (I am unsure 
how many rows it has)

Then the office installer is doing an Insert on the table as TEMPORARY.

r = table_create_new_row( view, &row, temporary );

returns a row of 0

then under the temporary case we do
idx -= tv->table->row_count

which is generating an idx of less than 0;


It looks like a wine bug. I can look into writing a test.
