Fix OSD to InventoryItem parsing

[mercurylinden]

Issue:

I noticed that my call to UpdateTaskInventory() was no longer updating the item in an object's inventory. I am finding the InventoryItem with GetTaskInventoryAsync(), modifying it and then passing it back to UpdateTaskInventory().

The issue is that GetTaskInventoryAsync() was changed to first try and use GetTaskInventoryViaCapAsync(), which relies on InventoryItem FromOSD() to parse the deserialized llsd from the RequestTaskInventory cap. InventoryItem FromOSD() is incorrectly parsing the OSDMap that is created in GetTaskInventoryViaCapAsync():

• ownerID is not getting parsed at all
• invType and assetType are being read as ints, but are strings in the OSDMap

So the wrong item data is getting sent to the simulator though UpdateTaskInventory(), and the simulator cannot update the item.

Verifications

• project builds
• all tests passing
• GetTaskInventoryAsync() provides a correct InventoryItem list.
