fix for expired keys during connection}
When you connect to live redis with lots of keys, after fetching keys some get expired, when it happens you get:
"[ERROR] TypeError: Cannot read property '1' of undefined
at getKeysInfo (/usr/lib/node_modules/p3x-redis-ui/node_modules/p3x-redis-ui-server/src/service/socket.io/shared.js:255:43)
at processTicksAndRejections (internal/process/task_queues.js:86:5)"
Redis returns type 'none' for expired/non existent keys.
