msi: Fix some copy/paste bugs in the implementation of condition operators.

[EA Durbin]

My analysis has not changed it still remains the same to this day.

Case, america's army installer is working backward, not going through the 
media in the correct order.

Upon troubleshooting this I found that this is due to the query returning 
the wrong results for LastSequence. I don't have an analysis for what is 
causing this yet. But this is what is causing the bug and I've never swayed 
on that.

I did in fact write a test, which does prove this. Hans has a copy of it, 
and i think i sent it to wine-devel too.

As for files.c, the query in ready_media_for_file() should be passing an 
unsinged integer as LastSequence must be greater than zero.

 >less than or equal to the value in the LastSequence column, and greater 
than the LastSequence value of the previous disk (or greater than 0, for the 
first entry in the Media table).
