luci-base: form.js: fix AbstractValue.textvalue() for uci list options

Browse source 
Serialize the uci list value into a space separated string before passing
it to String.format() for HTML escaping. Without that change, empty strings
were returned whenever the underlying uci get operation yieled an array.

Fixes: #4993
