Bug 10761: (follow-up) remove inadvertant dependence on Perl 5.14

As with commit 8f933bc04, Perl 5.14's support for array and hash
container functions accepting hashrefs and arrayrefs is a syntax
error in Perl 5.10.

To test:

Verify that t/db_dependent/Reports_Guided.t passes when run under
a Perl version older than 5.14.
