po2json errors on possibly duplicated ids even when verbose format is used

[jesenko]

If I understand correctly, this warning

Duplicate msgid ("Something: ${ employee.name }" and "Something: ${ employeesStr }" in the same context will be interpreted as the same key...

is relevant only if ttag po2json --format=compact

If verbose format is used, there should probably be no warning, or at least execution should proceed?
