On iOS, when using setItem on an undefined value, previous items are removed

See original GitHub issue

We found a problem that seems to occur only on iOS. When an undefined value is saved using setItem, previous values saved to keychain are removed. Values added after are saved as they should.

Adding values to keychain

SInfo.setItem('valueThatWillNotAppear', 'thisValueDoesntSave', {});
SInfo.setItem('secondValueThatWillNotAppear', 'thisValueAlsoWontSave', {});
SInfo.setItem('valueThatIsUndefined', undefined, {});
SInfo.setItem('valueThatWillAppear', 'thisValueSaves', {});
SInfo.getAllItems({}).then(values => {
    return values;
});

Resulting keychain values

Am I doing something wrong here? I know that I should verify that the value is not undefined but this behavior was definitely not expected.

Holy fucking shit, we just spent 4hours trying to figure out a VERY weird behavior, only to find out that the developer of this fucking library has not even spent the probably 2min that would take to solve this fucking issue. FUCKING FUCK
