Outliers: Multiple class value error instead of No class value error

[ajdapretnar]

Orange version

3.5.dev

Expected behavior

Outliers returns a correct error message. If there are no class values in the data, it says 'Data missing a class variable'.

Actual behavior

Outliers returns 'Multiple class data is not supported.'

Steps to reproduce the behavior

File (iris) - Select Columns (move iris to metas) - Outliers.

Can't reproduce this exact problem, but Outliers ignore classes.

This can be reproduced in 3.6.0. See #2647 .

Indeed, but this was a rather superficial fix. Outliers consider only X anyway. #2677 does it better.
