Make Query widget execute when Enter is pressed

[JosephRhodes2]

Make the Query widget execute when Enter is pressed after entering a query term, instead of needing to click "Apply".

This is a minor complaint, but also seems like an easy fix to make it match the behavior of the Query widget in WAB.

I was just about to suggest this idea as well. It's a shame it has yet to be implemented. Makes it more tedious for our end users to have to click "apply" when performing a query in our applications.
