Bug when {. $== $var} will return substitutions item length -1 items.

[xpol]

it('$== should work with substitutions', () => {
    const array = ['a', 'b', 'C', 'hi', 'ho', 'xi', 'big', 'pig', 'ball', 'cake', 'path/to/a.m4a', 'path/to/b.jpg']

    let resources = JSPath.apply('.{. $== $ext}', array, {ext: ['.m4a', '.jpg']})
    expect(resources).toEqual(['path/to/a.m4a', 'path/to/b.jpg'])
//    Received:
//      resources: ["big", "pig", "path/to/a.m4a", "path/to/b.jpg"]


    resources = JSPath.apply('.{. $== $ext}', array, {ext: ['.m4a', 'jpg']})
    expect(resources).toEqual(['path/to/a.m4a', 'path/to/b.jpg'])
//    Received:
//      resources: ["hi", "ho", "xi", "big", "pig", "path/to/a.m4a", "path/to/b.jpg"]
})

Depends on the string length in ext, all items with length - 1 in array will returned.

• When ext is ['.m4a', '.jpg'] the length are all 4, so all items in array have length 3 will also returned that is "big", "pig"
• When ext is ['.m4a', 'jpg'] the length are 4 and 3, so all items in array have length 3 and 2 will also returned that is "hi", "ho", "xi", "big", "pig"

Tested with jspath 0.3.3.
