"Module not meant for this backend" error moves it to "(default module)"

[quintesse]

To reproduce:

• Create a project and only enable the JS backend
• Create a module called javaimport
• Mark its module descriptor native("jvm")
• Observe how Eclipse moves the module to "source/(default modules)"

Just to be sure, with point 3 I simply mean:

native("jvm")
module javaimport "1.0.0" {
}
