[BUG] - Issue When Using Source Copy

[andilippi]

Describe the bug
When importing a scene with an advanced mask on that uses the Mask Type 'Source' It doesn't seem to load the source in. The text for the source name is there, but it doesn't do anything until that source is selected again.

To Reproduce
Steps to reproduce the behavior:

1. Copy a scene with an advanced mask on with Source Copy.
2. Paste it into another OBS.
3. You will see the advanced mask isn't linked

Expected behavior
I'd expect the mask to work
