Describe the bug

When using the cmd tool, a lot of memory leaks are shown at exit.
Not all singletons are freed, it shows registered singletons GdUnit4CSharpApi, GdUnitThreadManager, GdUnitDefaultValueDecoders but only GdUnit4CSharpApi and GdUnitDefaultValueDecoders is freed.

So there is a bug in the singleton manager.

Exit code: 0
----------------------------------------------------------------
Cleanup singletons ["GdUnit4CSharpApi", "GdUnitThreadManager", "GdUnitDefaultValueDecoders"]

        Unregister singleton 'GdUnit4CSharpApi'
        Free singleton instance 'GdUnit4CSharpApi:<Object#95210702280>'
        Successfully freed 'GdUnit4CSharpApi'

        Unregister singleton 'GdUnitDefaultValueDecoders'
        Free singleton instance 'GdUnitDefaultValueDecoders:<Object#142170130109>'
        Successfully freed 'GdUnitDefaultValueDecoders'

Hint: Leaked instances typically happen when nodes are removed from the scene tree (with `remove_child()`) but not freed (with `free()` or `queue_free()`).
