Subject: [PATCH] Ensure WiFi.localIP() is converted to a string when needed.
 (#455)

Due to a potential compiler issue (e.g. Platformio vs. Arduino IDE) it
seems that WiFi.localIP() wasn't being automatically associated with the
string varient when used in a string context.
Forcing the conversion should fix it in all cases.

Fixes #452
