[EuiSuperDatePicker] Clicking “Now” tab changes the value

[formgeist]

It is a bit surprising that simply clicking the “Now” tab is an action that changes the value, without any confirmation, or possibility of undoing.

So what's happening here is that now = 0 seconds ago which is what the Relative tab changes back to. It's the same way we try to persist the currently selected time in a relative fashion even when it's an absolute date:

I'm not sure what the call should be here. @nreese @snide Thoughts?

Perhaps instead of having a tab/button option, make "Now" an option in the Relative pane?

I'm going to try to come up with some ideas/mocks.
