Bug 42547: Fix SIP performance if sip2_resource_last_modified not set in cache 
In Koha, the sip2_resource_last_modified key is updated any time the SIP config is edited from the SIP2 editor in the staff interface ( institutions, accounts, system preference overrides ).

If sip2_resource_last_modified is missing from memcached, Koha SIP emits "Couldn't find sip2_resource_last_modified, considering configuration not up to date" in the logs, and fetches the entire configuration from the database, *for each request*.

This causes SIP performance to drop significantly. In my production testing with 83 institutions and 171 accounts the login message response time dropped from 0.283 seconds to 2.899 seconds.

I think the solution is pretty simple. If there is a cache miss on sip2_resource_last_modified, SIP should load the config from database as it does already, but then it should also set sip2_resource_last_modified!

Test Plan:
1) Apply this patch
2) Prove t/db_dependent/Koha/SIP2/SIP2ModuleMigration.t
