[BUG] UI values are not set on new SwarmInputs

[henrique-galimberti]

Steps to reproduce:

1. Create a SwarmInput on a Custom Workfow (with some default value).
2. Attach a logger node (or use its value in something you can verify later if it's indeed using the correct value).
3. Load the Custom Workfow to the Generate tab.
4. Change the value of the SwarmInput in the Generate tab.
5. Generate an image.

The value set in the input of the Generate tab for that SwarmInput will not be used. Instead, the default value of the SwarmInput (or null if it doesn't have an value) will be used (tested with a logger node and as a text for a prompt node).
