Webroot issue when '/'

[sinopsysHK]

domoticz version: 2023.1 Build Hash: f9b9ac774 Platform: docker on Ubuntu 20.04.5

If domoticz is launched with init parameter "-webroot /" it will lead to some issues with domoticz url used internally (http://127.0.0.1//) by dzEvent which will not be able to connect to API.

Exemple (current linuxserver.io container default):

/usr/bin/domoticz -approot /usr/share/domoticz/ -dbase /config/domoticz.db -noupdate -sslwww 1443 -sslcert /config/keys/server_cert.pem -userdata /config/ -webroot /

With such setup updating device status via dzEvents scripts raise following error:

this is due to bellow code: https://github.com/domoticz/domoticz/blob/225506eef4c24fdb2c7b285d7aa38e4b2b947c1e/dzVents/runtime/EventHelpers.lua#L71-L74

'/' is neither nil neither empty string but should be considered as such.

Solved in the next beta version. But if you look at the Domoticz help example you see it does not need a forward slash Thanks for noticing!
