"Spaces" should be automatically stripped from search query

[mikedemarais]

When searching on app.ens.domains, if a user's search query string includes a "space" it will return an error Domain malformed. ____ is not a valid domain.

Instead, the search input should automatically strip all "space" characters from the query string.

For example: a query for mike demarais or mikedemarais should both return search results for mikedemarais

I created this issue in this repo because the parseSearchTerm function used in ens-app lives in this repo.
