fix(dev): remove host configuration

Hosts configuration files might not only be used for mcp configurations.
Hence, the remove operation might must not delete the file altogether, but simply clear the mcp field.

- Replace the `unlink()` call by the creation of an empty `HostConfiguration` and write it to the host configuration file.
