What this pr does
Fixes very slow response when search.query.allowedSites = __all, esp. on multi-site installations.
How to test
Add a couple of extra sites with their own domain or subdomain and measure the time it takes for the method getDomainListOfAllSites to complete. Without the patch, this could easily run up to 0.3 or 0.5 seconds for each domain. With this fix, the time is negligible (and so it should, because this method is process uncached).
Fixes: #3292
