Lava can only turn concrete powder into concrete when it falls into source block

The bug

Concrete powder only turns into concrete when falling in lava source block. This is inconsistent with water where it turns into concrete when:

• touching water
• falling in any level of water

Code analysis

The method BlockConcretePowder.onEndFalling(world, pos, state, state) tests if the block is a liquid and turns the powder into concrete. The method BlockConcretePowder.func_192425_e(world, pos, state) only tests if the block is water.
