Add an end to end test to verify that the generated application works in development mode

[Shpota]

Aе the moment we have end to end tests that verify the application works in production mode.

At the same time, if there is a bug in docker-compose-dev.yml it won't be caught. This case can also be tested by running a database, staring a server (with go run server.go) and the front end with npm.
