Task Manager: 'ipywidgets.widgets.utils' has no attribute 'format_elapsed'

[tutuca]

Hi!. Thanks for the great library!

I happen to have an issue when using the task manager. Maybe it's a known issue.

It triggers in every tab of the task manager with non zero items (screenshot below).

It's possible version mismatch for some api that was deprecated on ipywidgets.

I could get it to work by making explicit imports instead of from traitles import *.

There are a couple of modules to review but I can get a PR in a couple more days. May be a bunch of test if I get some time.

Regards.

Hola @tutuca!

yes, probably that's the issue. I haven't used it for a while now, so I haven't had the change to get the same error. A PR would be great! Thank you
