Docker plugin overwrites entrypoint

Since I updated QtCreator to version 15.0.0 the Docker Plugin overwrites the container entrypoint even if the checkbox is disabled.

This results that my dev container does not load the SDK´s environment file to provide the build Kit. 

Even if I manually overwrite the entryoint as a additional parameter, the environment is not loaded.

In the appendix, you will find an Image with the configuration I use.
