Bug 14468: followup to fix tests
This patch fix an expected test result.
Also changes a comparison for the return value to 'delete'
layout sub, in case of success it returns 'undef' and triggers
the message 'use of uninitialized value $del_results ...'
To test:
1) Whitout this patch
prove t/db_dependent/Labels/t_Layout.t
fails.
Also note the message
"Use of uninitialized value $del_results in string ne at t/db_dependent/Labels/t_Layout.t line 110."
for using the return value of delete layout (undef on success!)
2) Apply the patch
3) Test pass and no more message
