Test IndexedDB's cursor value property.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

PASS cursor.key is expectedKey

Check expected values:
PASS cursor.value.a is expectedA
PASS cursor.value.b is expectedB
PASS cursor.value.foo is undefined

Modify values:
cursor.value.a = 3
delete cursor.value.b
cursor.value.foo = 'bar'

Ensure modifications are retained:
PASS cursor.value.a is 3
