Using import hints for glTF 2.0 files breaks animation references

[linky00]

Godot version:
3.2.1.stable.official

OS/device including version:
Windows 10 Home v1903

Issue description:
When importing a glTF 2.0 file, Godot will recognise import hints to objects such as '-col', adding features such as a collision node and removing the hint, so for example 'Marker-col' turns 'Marker'. However, the animation references aren't changed, so you get an error such as:

Node not found: Marker-col.
On Animation: 'Marker-loop', couldn't resolve track: 'Marker-col'.

Steps to reproduce:

Create a .glb file with an object with a hint, and animations involving that object. Import it into Godot, open it, click on the AnimationPlayer, and the error will occur and the animations will not work.
