The symfony version is 3.3.6 and it's a clear installation. Maybe there is the problem.
Im not an expert in symfony and github either and Im spanish (excuse me about my english level).
Please, tell me if you need more details about code and versions.

Thanks.

Problem solved in IRC with using

{
    ...
    "autoload": {
        "psr-4": {
            "": "src/"
        },
}

instead of

{
    ...
    "autoload": {
        "psr-4": {
            "AppBundle\\": "src/AppBundle"
        },
}
