Fix AbstractSearchableSnapshotsRestTestCase.testClearCache (#58847)

Since #58728 part of searchable snapshot shard files are written in cache 
in an asynchronous manner in a dedicated thread pool. It means that even 
if a search query is successful and returns, there are still more bytes to 
write in the cached files on disk.

On CI this can be slow; if we want to check that the cached_bytes_written 
has changed we need to check multiple times to give some time for the 
cached data to be effectively written.
