Color picker resets on reload

[oie669]

What are the steps to reproduce?

1. Add a color picker widget with "Send" set to "multiple values during editing"
2. Deploy
3. View the dashboard
4. Pick a color
5. Refresh the page twice

What happens?

On the first refresh, the color picker state is cleared, but the dashboard UI does not display the update.
On the second refresh, the cleared color picker state is properly shown.

Here is a debug of the message payloads at each point:

Set color in dashboard

12/1/2018, 7:31:53 PMnode: 341cbb14.e8efd4
msg.payload : string[6]
"ff1818"
12/1/2018, 7:31:53 PMnode: 341cbb14.e8efd4
msg.payload : string[6]
"ff1818"

Reload first time

12/1/2018, 7:32:12 PMnode: 341cbb14.e8efd4
msg.payload : string[0]
""
12/1/2018, 7:32:12 PMnode: 341cbb14.e8efd4
msg.payload : string[0]
""

Reload second time

12/1/2018, 7:32:26 PMnode: 341cbb14.e8efd4
msg.payload : string[0]
""

What do you expect to happen?

The color picker state should persist between reloads. Note: setting "Send" to "one value when released/closed" behaves as expected.

Actually I think the bug is slightly different... it should not be cleared at all - it should retain the set value no matter how many times it's reloaded - as it does when in "one value" mode.
