CLDC-3487: Ensure locations and previous_la_known are cleared when necessary (#2452)

* CLDC-3487: Clear previous_la_known when necessary for renewal logs

* CLDC-3487: Clear location when clearing scheme due to org change

* CLDC-3487: Use nil instead of 0

* Specify orgs on sh logs when needed for tests

* Fix flaky tests
