bless polonius output of test ui/nll/outlives-suggestion-simple.rs

The polonius output has one more error which should be displayed
in the regular case, but error reporting in the regular case stopped
at the first error.

Admittedly it would be nice to combine suggestions for the same source
lifetime so that `'a: 'b` and `'a: 'c` are not bothsuggested, but instead
a single `'a: 'b + 'c` is.
