Minor fixes in console errors when running unit tests

[maludwig]

This fixes warning messages that were annoying and confusing me in my personal project about "defaultChecked" being set at the same time as "checked" is set, mostly, they also appeared in the console error log when running the unit tests. So I fixed those ones, and then got carried away and solved all of the warnings in the unit tests. The following error/warning messages were resolved:

Warning: Control contains an input of type checkbox with both checked and defaultChecked props. Input elements must be either controlled or uncontrolled (specify either the checked prop, or the defaultChecked prop, but not both). Decide between using a controlled or uncontrolled input element and remove one of these props. More info: https://fb.me/react-controlled-components
Warning: Each child in an array or iterator should have a unique "key" prop.

Check the top-level render call using <Connect(Form)>. See https://fb.me/react-warning-keys for more information.
