Catch or repair error if spatialTools folder contains corrupted objects

[benptc]

Reported error of server crashing on launch:

C:\Users\break\OneDrive\Dokumente\vuforia-spatial-edge-server\libraries\hardwareInterfaces.js:145
for (var key in objects[objectID].frames[objectID].nodes) {
^
TypeError: Cannot read property ‘nodes’ of undefined

What i did to track down possible errors was to take out every .index -file that is stored in my Spatialtoolbox/Object/interface folder. After deleting the interface folders, the server started again.

Response:

I believe the cause of this error is that there is something broken with your objects. Objects are stored in documents > spatialToolbox > [NameOfYourObject] > .identity > object.json
If your object exists but this file is missing or broken, you could potentially get such an error.

We could verify the integrity of all objects when the server starts, and either repair or disable them if they're broken and report the error gracefully.
