[BUG] [EDITOR] Constraint Manager's button "Go to component" doesn't work for custom TransformConstraint

[anonymous2585]

Describe the bug

When using a custom script that extends TransformConstraint, the "Go to component" button in the Constraint Manager doesn't work when clicked.

To reproduce

Steps to reproduce the behavior:

1. Import this script

using MixedReality.Toolkit;
using MixedReality.Toolkit.SpatialManipulation;

public class CustomConstraint : TransformConstraint
{
    public override TransformFlags ConstraintType => TransformFlags.Rotate;

    public override void ApplyConstraint(ref MixedRealityTransform transform)
    {
        // not necessary for this issue
    }
}

2. Open scene HandInteractionExample
3. Add this constraint on one of the ObjectManipulator
4. On the Constraint Manager, click on 'Go to component' for the custom constraint
5. See warning Item Custom Constraint not found in window Inspector.

Expected behavior

The component is highlighted just as the built-in components.

Your setup (please complete the following information)

• Unity Version 2021.3.21f1
• MRTK Version or Commit main@d818d18

Additional context

• When changing $"{ObjectNames.NicifyVariableName(constraintName)}" to $"{ObjectNames.NicifyVariableName(constraintName)} (Script)" in ConstraintManagerEditor.cs, the custom component is highlighted but break for MRTK's constraints.
• User work-around is to add [AddComponentMenu("MRTK/Spatial Manipulation/CustomConstraint")] attribute on the class. It changes the displayed name in inspector and removes the " (Script)" part. But it's better if this feature works out of the box for all scripts.

@AMollis thinks this may be a dupe. Investigating.

I was thinking of this issue

• Go to component button on Object Manipulator not working #313

The #313 issue is slightly different than this new issue.
