Bug 38148: Revert back to get_effective_rule

And update the first conditional logic.
This patch aims to maintain the logic behind the first patch, but restore get_effective_rule.
get_effective_rule_value is using cache and I believe that is the reason why Items.t fail when using that.

Test plan:
1) Search for 'music' on OPAC
2) Notice records have the 'place hold' link
3) Visit circulation rules on Staff:
<staff_url>/cgi-bin/koha/admin/smart-rules.pl
4) On 'Default checkout, hold and return policy' , under 'Hold policy' pick 'From any library'. Hit 'Save'.
5) Repeat 1). Notice the 'place hold' link is gone.
6) Apply patch. restart plack. Repeat 1). Notice the 'place hold' is shown again

Run:
$ prove t/db_dependent/Koha/Items.t
