Bug 25296: Make ->empty work for uninstantiated calls

In OO we would usually instantiate the class and then interact with it
like in:
    my $rs = Koha::Patrons->new;
    $rs->empty;

Koha's practice is to call things like Koha::Patrons->search without
instantiating the Koha::Patrons class. To keep consistency, this patch
instantiates the resultset object on behalf of the caller if required.

To test:
1. Apply the tests patch
2. Run:
   $ kshell
  $k prove t/db_dependent/Koha/Objects.t
=> FAIL: Tests fail because it is expected to have the class
instantiated
3. Apply this patch
4. Repeat 2.
=> SUCCESS: Tests pass, instantiation happens implicitly.
5. Sign off :-D
