Unicode, DBIC Tests

Hi, it's me again.
I noticed that DBIC threw some warnings while running the unit tests complaining about non-integers and undefs passed to find(). This pull request fixes that.
Furthermore I found out why the last test (Unicode wikilinks) in unicode.t failed: In lib/MojoMojo/Schema/ResultSet/Page.pm I found explicit calls to decode_utf8().  If removed the test passes.
Is there really still need for a decode call?
