Fix GLCanvas Recreation - Regression 96af6c9bf2d683115996

96af6c9bf2d683115996 moved the creation of the AWTGraphicsConfiguration,
GLDrawable and GLContext to the GLCanvas constructor.
This disabled recreation, removeNotify()/addNotify() after 1st addNotify(),
since the drawable/context were already set to null.

Smart recreation, ie not destroying the resources completly:
    1 - drawable
    2 - context
    3 - AWTGraphicsConfiguration's Device (X11: Display)

is not possible, since removeNotify() is the only destroy notification
we have from AWT, which would leave the above resources open -> leak.
This is especially true for (3), since the device is created 'on the fly'.
In NEWT we use lazy creation/destroy and are able to keep the references alive.
A remodelling of AbstractGraphicsConfiguration would be required,
which indeed would be overkill.

Simple solution is to move the creation block back to addNotify()
but before 'super.addNotify()', since it needs our chosen AWTGraphicsConfiguration.

Also flagging sendReshape in addNotify().

Added test case com.jogamp.test.junit.jogl.awt.TestAWT03GLCanvasRecreate01.
