Scenario:

Using negative ranges to query last N elements of an array you get more elements than in the array itself if the array's length is smaller than N.

Steps to Reproduce:

Query $[-10:] on a [1, 2, 3] array

Expected Result:

>>> [m.current_value for m in Path.parse_str('$[-10:]').match([1, 2, 3])]
[1, 2, 3]

>>> [m.current_value for m in Path.parse_str('$[-10:]').match([1, 2, 3, 4, 5, 6, 7, 8])]
[1, 2, 3, 4, 5, 6, 7, 8]

Actual Result:

>>> [m.current_value for m in Path.parse_str('$[-10:]').match([1, 2, 3])]
[1, 2, 3, 1, 2, 3]

>>> [m.current_value for m in Path.parse_str('$[-10:]').match([1, 2, 3, 4, 5, 6, 7, 8])]
[7, 8, 1, 2, 3, 4, 5, 6, 7, 8]
