Fix opening a non-primary .ino file

When a sketch looks like this:

    Blink/
        Blink.ino
        Foo.ino

The idea is that opening Foo.ino should open up the sketch. However,
before this would show an error stating "The file Foo.ino needs to be
inside a sketch folder named Foo" instead.

This turned out to be due to a typo, which seems to have been present
for a long time. Note that when the main sketch file was a .pde file,
everything already worked as expected.
