Unable to change rendered aircraft model in versions newer than 0.15.46

[ltoenning]

Description

When attempting to change the model matching/rendering for an aircraft while online, swiftGUI refuses to apply the change. Instead, it reports that the aircraft is “already matched”, preventing the new model from being assigned.

Steps to Reproduce:

1. Go online in swiftGUI.
2. Open the Models page.
3. In the Rendered aircraft list, select an aircraft within range.
4. Switch to the Aircraft models tab.
5. Click Load model set.
6. Choose a model from the loaded model set to replace the rendered one.
7. Click Save.

Affected Versions:

• Works in: 0.15.46 and older
• Broken in: 0.15.72 and newer

I found a change in the code /src/gui/components/mappingcomponent.cpp that initially caused this error.
