  Fix for bug #7223: information_schema: error in "views"

The error is older, as I got it already yesterday but did not yet report.

How to repeat:
Run the test suite.

The bug was due to that there was a 0.001 factor added to the cost in the new
greedy optimizer, but it was not added to the old optimizer.
