Fix null sampler warning in TextureTest.TextureNPOT_GL_ALPHA_UBYTE
The test deliberately tries to render a scene using an invalid texture.
ANGLE rendered this correctly, but when it bound the dummy 1x1 black texture
that's used instead of invalid textures, it didn't bind a sampler state. This meant
that D3D had no pixel shader samplers bound, and outputted a debug warning.
Also, technically the test should have been setting GL_UNPACK_ALIGNMENT=1,
but that wasn't impacting the result of the test.
