Ignored Seconds-Change

[EaseRider]

Hello again, thank you for this project.

Environment

Tech	Version
material-ui-pickers	any (beta-14 currently)

Steps to reproduce

1. DateTimePicker or TimePicker
2. format='DD.MM.YYYY HH:mm:ss' or 'HH:mm:ss'
3. Only change Seconds with keyboard
4. open Picker

Expected behavior

Changing the Seconds should also fire the event, with the new time; maybe parsed by the format.

Actual behavior

Chaning the seconds does not fire the event. So the old value is taken when opening the picker.

Doesn't seem to be solved to me.
the error may lie on line 199 in DateTextField.jsx
if (!error && utils.format(newValue, 'LLLL') !== utils.format(oldValue, 'LLLL')) {
Where LLLL formats the date into 'Monday, March 26, 2018 9:31 AM' where the seconds (and millis) are missing.
Something like: 'YYYY-MM-DDTHH:mm:ss.SSSZ' would be the most accurate. But I don't think that the Z would be needed to compare the timezones of the input.
