some fixes

[MichaelDvP]

• custom entities commands not working, (entityItem.name.c_str() is local and not permanent)
• customizations naming with tags was odd, now change name but keep the tag.
• terminal call does not show info/values for ems devices anymore

didn't know about the custom entities and tag, nice fix.

For the console, what was the issue with the show info/values from the console? I'll add it to the unit tests.

what was the issue with the show info/values from the console

before the commands info/value/commands were registered for each ems-device, now these commansd are handeled by get_value_info and do not show in register.

No info/values/commands in boiler, thermostat, mixer, solar, etc.
With the fix it shows the commands. It's not an important fix.
