disabled an object in viewport confuses modifiers during export

[xriss]

Describe the bug
If an object is "disabled in viewport" and you export with modifiers applied, then modifiers are not applied to that object.

A bit obscure and personally I'll just stop using disable in viewport to work around it, (I was only using disable in viewport to work around an old issue with the collada exporter )

Just thought I would flag it as slightly strange behaviour.

To Reproduce
I've included an example blend files with two identical cubes that have a mirror modifier, one of these objects has been disabled in viewport.
Export with modifiers applied and take a look at the output gltf, it is obvious from the accessor array that one of the objects has half the vertexes of the other when they both should have had the same mirror modifier applied to them.

Confirmed.
Probably linked to depsgraph evaluation.
