Wrong the value is not a string warning on multiRemove

[Bardiamist]

Current behavior

Warning

Expected behavior

No warning

Repro steps

AsyncStorage.setItem('a', '1').then(() => {
  AsyncStorage.multiRemove(['a']);
});

Environment

• Async Storage version: 1.7.0
• React-Native version: 0.61.5
• Platform tested: iOS
• Logs/Error that are relevant:
  [AsyncStorage] The value for key "a" is not a string. This can lead to unexpected behavior/errors. Consider stringifying it.
  Passed value: 0
  Passed key: a

I'm also seeing this warning pop up on iOS and Android when I call multiRemove with keys that currently have no value stored.

So, for me, on version 1.7.0 the following happens:

AsyncStorage.setItem('obj1', '{"prop":"val"}')
  .then(() => AsyncStorage.multiRemove(['obj1']))
  .then(() => AsyncStorage.multiRemove(['obj1']))

On the second call to multiRemove, I get a yellow box saying

[AsyncStorage] The value for key "obj1" is not a string. This can lead to unexpected behaviour/errors.
Consider stringifying it.
Passed value: 1
Passed key: obj1

Since I'm not setting the value of obj1, this should not appear, right?

Will look into it, thanks for reporting.
