Changes required for esp32-1.05 library upgrade, line 250

[jameszah]

Two things:

1. esp32 now needs the insecure stated, so put this as the last line of setup()

client.setInsecure();

2. Somebody changed ssl_client or mbedtls_ssl_write, so this line is now bad:

https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/blob/65e6f826cbab242366d69f00cebc25cdd1e81305/src/UniversalTelegramBot.cpp#L250

And needs to be changed to:

client->println();

Its purpose was to send another cr-lf (2 bytes), but what it was actually doing was sending a 0 byte message, then the 2 byte message, but ssl_client.cpp, which calls mbedtls_ssl_write(), declared a fatal error after the 0 byte message.

Still haven't learned how to do a PR 😄 Here is some demo code: https://github.com/jameszah/ESP32-Cam-Telegram I'll update my versions of the library from last summer with the fix.
