Avoid an "OpenGL Error: 1282" output when resizing a QOpenGLWidget

Browse Source 
When we delete the previous FBO in QOpenGLWidget::resizeEvent while
it is the currently bound FBO, the QOpenGLContextPrivate::current_fbo
will not be updated and will try to be bound during the initialization
of the new FBO.

Fix the issue by explicitly releasing the FBO on destruction if it
is current.
