a11y atspi: Report app parent

Browse Source 
While the application's a11y object doesn't have a parent
within Qt's a11y hierarchy, the AT-SPI registry/desktop is the
parent of all application objects.

Therefore, report that one instead of using a null path.

With that in place, querying the application parent
via Accerciser's IPython console now gives the expected
result:

    In [16]: acc.role
    Out[16]: <enum ATSPI_ROLE_APPLICATION of type Atspi.Role>
    In [17]: acc.parent
    Out[17]: <Atspi.Accessible object at 0x7fbebc3fc1c0 (AtspiAccessible at 0x139d6410)>
    In [18]: acc.parent.role
    Out[18]: <enum ATSPI_ROLE_DESKTOP_FRAME of type Atspi.Role>

While at it, also add a "m_" prefix for the
AtspiAdaptor::accessibilityRegistry member.
