[Bug] Resetting a search query and reload will result in empty page

Steps to reproduce:

1. Enter a search query in one of the 2 search inputs and submit the search. -> The results will be displayed and the search query will be displayed in both search inputs.
2. Reset the query (by clicking the cross icon in the input) and submit the search by clicking the input's search icon again (which input you interact with doesn't seem to be important, the bug will appear in both inputs). -> The page will be empty except for the menu and the side panel.

Other way to reproduce:

1. Search any query term.
2. Delete the query parameter value in the url and reload.
