Nick Craig-Wood c47a4c9703 opendrive: re-read hash when updating objects
Previously this was reading a stale hash from the object leading to
broken integration tests.

This fixes these integration tests TestSyncDoesntUpdateModtime,
TestSyncAfterChangingFilesSizeOnly, TestSyncAfterChangingContentsOnly,
TestSyncWithUpdateOlder, TestSyncUTFNorm.
