bug #6822 Adjust Application use statement (kvdnberg)

This PR was submitted for the 3.1 branch but it was merged into the 2.7 branch instead (closes #6822).

Discussion
----------

Adjust Application use statement

The code example assumes the use of the Console Application (no kernel parameter) but the use statement is for the Frameworkbundle Console Application, which requires the kernel parameter. This is confusing, basically the example cannot work as it is.
