This change was necessary to run this test at all.
Test finding dates.

Finding one record with a date works. findAll does not load the dates.
Do not normalize twice.

The individual records in an array were being normalized in
extractSingle, then normalized again in extractArray. #normalize is not
idempotent and the second normalization caused previously deserialized
dates to be set to null.
When this test is enabled, the runner loops forever.

I don't know why, but since its pending anyway it doesn't seem worth
investigating right now.
Ensure that dates (etc.) in associations are deserialized.
Merge pull request #18 from humanpractice/find_all_dates

Date attributes were set to null with findAll
