Painting entities are not removed correctly from the client

If an existing Painting entity is removed, and it is created again using the same Entity ID, it causes a client crash. This behavior is not shown on other entities, where they are created correctly.

This was discovered during world teleporting between different worlds in PocketMine-MP. After reproducing the problem, I discovered that it was caused by the client.

The steps to reproduce it (for developers) are:

• Create a new painting entity using AddPaintingPacket (0x99)

  99000000020000007e0000004400000081000000010003536561
  Entity ID: 2
  Spawn X: 126
  Spawn Y: 68
  Spawn Z: 129
  Direction: 1
  Title: Sea

• Remove the entity using RemoveEntityPacket (0x8d)

  8d00000002
  Entity ID: 2

• Add the painting again using the same packet as the first step (time doesn't matters)

• Instant crash

Packet values are an example

This could affect MCPE 0.9.0 and infinite worlds, because if an entity is removed from memory, and you return to that area, a crash will happen.

Android devices, and Creative mode is also affected.
