Update site cache clearing to switch to blog before site cache is cleared. In most cases we will already be in the current blog due to how the Cache_Enabler::each_site() method functions, but this will fix the known issue for multisite networks discussed in PR #170 where some cache cleared hooks would not be fired or the values would be empty. This would occur when using the WP-CLI clear subcommand with the --sites option or the public clear cache hooks like cache_enabler_clear_site_cache_by_blog_id when the blog ID being cleared is not the main site.
