[gobject-introspection/ebassi/property-annotation: 17/19] Improve getter function matching heuristic

[Emmanuele Bassi <ebassi src gnome org>]

commit 03059895809eb7061175b90bf8231096ac59fdc8

    Improve getter function matching heuristic
    
    Some readonly boolean properties in the form of 'has-foo' or 'is-bar'
    expose a getter function in the form of `get_has_foo()` or
    `get_is_bar()`, according to extant coding practices. We should ensure
    we still check for those.
