Prevent a crash when no cursor drawable is set

Summary:
React Native 0.43 added additional functionality to setSelectionColor that also tints the cursor drawable of the View. However, some views may not have a cursor drawable set in which case, the code will crash when attempting to load a drawable with resource id 0.

We encountered this in our RN 0.45 upgrade in the Airbnb app.
