Mobile search component shows filters in SSR and results in CSR

[ybnd]

Describe the bug

When opening DSpace on the /search page (or any page with a search component), the SSR HTML is focused on the "Search Tools" part of the page. As soon as CSR kicks in, it switches to the search results instead.

To Reproduce

Open https://demo.dspace.org/search in a new tab

• At first, you'll see the "Search Tools" (after Exclude search and browse components from Angular SSR #3709, this will be a "skeleton loader")
• This will be quickly replaced by the search results

Expected behavior

The SSR HTML should be representative of the final view shown in the browser.
