Remove showNoResultsComponent

[dirkcuys]

The variable isn't used in BrowseLearningCircles. If you wish to disable it, you can simply pass an empty fragment as the NoResultsComponent:

const NoNoResultsComponent = props => <></>

Or figure out what happened to it?
Seems like it was initialized based on how the search page is used: https://github.com/p2pu/p2pu-components/blob/master/src/Search/SearchProvider.jsx#L164

But it doesn't actually get used: https://github.com/p2pu/p2pu-components/blob/master/src/Search/SearchProvider.jsx#L176
