Run example tests during CI build

[mdjastrzebski]

Describe the Feature

Currently the CI checks include RNTL own tests. Proposed feature is to also run any integration tests included with example projects.

This would allow as to test integration with popular libraries, e.g. React Navigation, Redux, etc without adding them as dev dev dependencies to the RNTL project.

Possible Implementations

Ideally example projects tests should use current version of RNTL, i.e. source found in the root directory, and not node package. This way CI would check if all test projects work correctly with RNTL code changes.
