Trailing newline character in path is not handled

[q2w]

Trailing newline character is not handled effectively while parsing a JsonPath. Consider below example,

jsonDocument:

{
  "level_0": {
    "level_1": {
      "level_2": "At level 2"
    }
  }
}

jsonPath: $.level_0.level_1.level_2\n

JsonPath.read(jsonDocument, jsonPath) would evaluate to null

This was handled earlier and was removed in this code change.
