Issue DM-3387: Make use of good pixel count when building CoaddPsfs
When building a CoaddPsf we have the ability to take account of the number of pixels contributed by the inputs (see http://ls.st/paj and DM-3258). However, the {{CoaddPsf}} constructor fails to use this information. It should copy this field when copying the provided {{ExposureCatalog}}, so that {{computeAveragePosition}} can use it.
