Fix search-result ssr

[hiagolcm]

What problem is this solving?

#639 removed the ssr:false flag from the search-result that was accidentally placed after deploying the AB feature.
This PR had to be deprecated due to layout shift issues

What we didn't know is that the variant variable was obtaining different results between SSR and CSR. In SSR the value for this variable is null, but for CSR, when the sp-variant cookie does not exist, the result was an empty string

This PR removes the ssr:false flag again and corrects the divergence in the variant variable.

How to test it?

Workspace
You can disable the javaspcript from you browser in order to check the ssr rendered page.
On chrome: Open dev-tools> press cmd+shift+p > type "disable javascript"
