[FIX] web: parse numebr (separator not set)

Steps to reproduce:
- select a language where thousands separator is not (e.g. portugese)
- try editing any number input field

Bug:
 error when parsing the new value when thousands separator is not defined

Fix:
 fixed default value (only fallback to commas if it's not the decimal
Point separator)
