improve basic example

[fabOnReact]

Feature-Request

Describe the Feature

I would like to assign this task to myself and upgrade the Basic Example to reactnative@0.61.5 for the following reasons:

1. The basic demo example is the main tool used to develop and test features for the react-native-camera library
2. The basic demo example is also used in Continuos Integration to run test on the device
3. Make the demo easier to install

Possible Implementations

1. Fix RunTime error when recording
2. Upgrade to react native 0.61.5 (solve bug)
3. Add permissions
4. Update dependencies
5. Review the metro.config.js and rn-cli.config.js configurations

Experienced on the master branch and while working on pull 2724

Probably because of something between 3.9.0...master. Did you got any progress on that?

@MateusAndrade I was working on upgrading the example app to rn0.61.5 but I'm postponing it.
