qmlimportscanner: Don't crash on invalid argument

Apparently you can pass one "root path" as a bare argument, but you have
to specify "-rootPath" if you want to pass more than one. The whole
concept of a "root path" is wrong. Therefore let's not add more ways to
specify root paths. It should not crash, though.
