Log Message:
-----------
fix: a crash on program exit if bones were used (#3037)
`ValueNode_Bone_Root` does not have a GUID and does not belong to
any canvas. Calling `get_guid()` for `ValueNode_Bone_Root` leads to
an attempt to insert it into a canvas (it calls `global_node_map()` for
this purpose).
And if `global_node_map()` is already destroyed at that moment, it
leads to a crash.
Since `ValueNode_Bone_Root` is also a static variable, it can be
destroyed later than `global_node_map()`.
I moved this variable inside `get_root_bone()` method, which changed
the initialization and destruction order.
I also added a check for `is_root()` for more correct behavior.
