Android: Fix OpenGL texture name leak

This fixes texture name leak when changing media player's source. Texture name
shold be deleted by OpenGLResourcesDeleter class, but when player's source is
changed OpenGLResourcesDeleter's texture name is reassigned with new one
without old name deletion.
This change deletes OpenGLResourcesDeleter's current texture name when new name
is assigned.
