Fixes bug in ofImage causing problems in loadImage

A previous commit moved the setting of width/height/bpp/type into
allocate(). While these values should indeed be set during
allocation, possibly before an update(), they should also be set
in the case that some other program flow results in an update()
without an explicit call to allocate(), as occurs when calling
loadImage().
