ownership when modifying and fetching entities

This was a cherry-pick of 40a01dbd63f4b7ea228759c843fe91f0902fdbd0.
The 000024.xml change ended up being discarded b/c
7fc13f1a96269501b8bb237ead716256f28b5b3c had already picked it up
in its entirety, so I just kept that file as is. Same for
masterChangeLog.xml. The MyGpsTaskControllerTest.java conflict was
just whitespace.
