getUpdateMetadata may return an empty string on android

[jer-sen]

Hello,

On android in some case, I get an empty string instead of a null value when I call getUpdateMetadata with no arguments.
It seems normal since the native android code resolves getUpdateMetadata as an empty string in some cases.
But in the documentation it's written that getUpdateMetadata return a LocalPackage or null...

If I'm right, can you update the documentation or fix the code ?

Thanks.

@Jay1337 - thank you so much for pointing at this.
I've added PR to fix this inconsistency (have tried this on emulator and real device with Android 7 and RN 0.44 and CP 2.0.3-beta) - could you please also verify if it works for you on your side?

@max-mironov I'm not able to test it but your PR seems ok
