[FIX] tests: properly log errors

If a test is failing with assertRecordValues, the comparison and the error
logging were not computed the same way.
The _compare_candidate was accessing the record via
record[field_name]
which uses the cache

While the _format_message was doing
records.read(...)
which queries directly the database.

If the test was failing (correctly) because of a wrong cache invalidation
(e.g. update the value directly in SQL without invalidating the cache),
the error message would look like:

AssertionError: Record doesn't match expected values at index 0.
Current values:
{'id': 42, 'name': 'Foo'}
Expected values:
{'name': 'Foo'}
