Issue when the object ins't included in the default collection

[Oxervision]

Hi Rombout, I'm learning Blender 2.8 and I installed your version of uvlayout_bridge and I found an issue if the object isn't include in the default collection. macOS 11.13.6 & uvlayout_bridge 0.6.4 & Blender 2.80.45 Error message:

Traceback (most recent call last):
  File "/Users/Oxer/Library/Application Support/Blender/2.80/scripts/addons/uvlayout_bridge/__init__.py", line 772, in execute
    UVL_IO()

AttributeError: 'Object' object has no attribute 'collection'

location: <unknown location>:-1

To Reproduce Steps to reproduce the behavior:

1. Select the object (whitout collection / included in antoher collection / different to default collection)
2. Click on 'Unwrap in UVlayout >'

It's very easy fix the issue, to move it to the default collection, for that it would be a good idea to add an alert when the object isn't included in the default collection. If the object is included in another collection, it appears the same error message.

@Oxervision , thanks for the finding. I had a quick look at it. I think for now ill leave this function out perhaps. I need to check and read up on how this all works in depth.

Thanks for the reply, are you working on TheaForBlender update for Blender 2.8?

Not yet, i want to do some more small addon before i tackle this big one.

Hi i think i got it now. I also fixed a other issue where i got an error when "use selection" was off. It would cause an error for none mesh types (camera, lights etc) Try this versions #bl2_80
