Fix EZP-23424: clear content/info/remoteId persistence cache

JIRA: https://jira.ez.no/browse/EZP-23424

When persistence cache is cleared (from legacy, through the `content/cache` event),
 cache for `'content', 'info', 'remoteId'` was not being cleared.

Tests: manual

TODO:
- [ ] Update / add tests
Also, I guess you did not test this, cause locationHandler only returns [SPI\..\Location], no ContentInfo there, so you can wipe out remoteid like you did a few versions ago. Cache\ContentHandler does the same.
