Pawn can move past another piece

Steps to reproduce:
1. Run App.java
2. Make the following moves:
   1. e4 e6 2. d4 e5 3. f4 e3

On the last move, e3, pawn is attempting to move up 2 pieces, and jump over another piece.

Expected result:
Move is invalid and therefore not executed.

Actual result:
Move is recognized as valid and executed.

Reason:
This bug was happening in one special case. Namely, pawn wants to go 2 squares up, but there is a piece which is one square up. Reason was that we forgot to test that there is no piece on one position up from the pawn. 

Resolution:

In case when pawn tries to move two squares up, I added condition that there is no piece one square above the pawn.
