Does not seem to work with Qucs develop branch

Qucs built from source: https://github.com/Qucs/qucs commit `c282c76`
Qucs-RFlayout built from source commit: `df19c3e`
OS: Ubuntu 24.04

Using the test file: ` qucsrflayout -i test/lpf/lpf.sch`

Output:
```
ERROR : A wire is used to connect more than two connection points.
        Please use a component like a tee or a cross to avoid this.
```

Qucs-s works without issues
