[Interchange] Crash on asset re-import

We've started seeing a crash in editor when re-importing one of our assets.
<pre class="ql-syntax">Assertion failed: (Index >= 0) & (Index < ArrayNum) [Link Removed] [Line: 783]
Array index out of bounds: -1 into an array of size 3
</pre>

But it goes into libfbxsdk and we don't have the symbols to debug it properly.

I haven't tried a vanilla project repro yet, but I have attached the fbx that is causing the crash when re-importing. I have confirmed it also crashing when importing so I'd expect it to crash on a vanilla project too as we don't have any engine changes in that area.

Try importing the FBX file provided through interchange. It should be imported without any crashes.
