Subject: [PATCH] Add guard to handle to check for _initialized (#1321)

The wifi stack initialisation must be complete before calling  `_udp_ota.parsePacket()` otherwise you just get a screen filled with
```
```
and due to the more async methods in ESP32 `handle()` may be called before this can occur.
