Adding a simple E2E test to check if we can enter and join a room and afterwards disconnect from it

Problem to solve

Within CI/CD it would be nice to have some automated tests to check if the example app is still working or not. These E2E tests are not meant to cover all possibilities, but at least check if the basics are working. Maybe we could at it to the CI/CD as well for some Android and iOS versions.

Proposal

It would be nice to have a E2E test with flutter driver to test if we can enter a room and join it.
