Bug 6475 - Edit it's not possible in subfield "0" in MARC framework

When trying to modify the subfield "0" on a field in the
MARC subfield structure admin -> Tag xxx Subfield Constraints,
the boolean condition on liblibrarian fails for the initial "0" value.
Modified condition to allow the value "0"
