Keyboard hook not unregistered because it is called on every patch change

[sagantech]

Describe the bug
Leaking hooks is not a good idea

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Surge'
2. Click on preset and select one
3. Repeat
4. Keyboard hooks are leaked, one for each patch change

Expected behavior
No Leaks. (BTW There are many memory leaks as well). Depending on the implementation, no crashing later when hook is called.

Additional context
In SurgeGUIEditor::openOrRecreateEditor This function is called:

frame->registerKeyboardHook(this);

Simple fix is to move to SurgeGUIEditor::open and not call this function from SurgeGUIEditor::openOrRecreateEditor.
