fix(test, mocks): extra comma syntax error in mock definition (#1134)
fix(test, mocks): extra comma syntax error in mock definition (#1134)

Just stumbled upon the error below when trying to start tests using 7.2.0:
```
SyntaxError: node_modules/react-native-device-info/jest/react-native-device-info-mock.js: Unexpected token (105:38)
```
Seems a trailing `,` made it into the code.
