qview Find tool still wrongly prioritizes camera model over map projection

[rvwagner]

ISIS version(s) affected: 8.3.0 and earlier

Description
I believe this is very closely related to #5508, but a slightly different expression of the same underlying issue. If you have a map-projected file with SPICE data covering only part of the image (I didn't realize this was even possible, but apparently that's what you get from map-projecting just the even or odd framelets of an LROC WAC image), then the Find tool does not correctly align linked images when you click in an area that is within the map projection bounds but does not have SPICE data. Alignment works correctly in places that do have SPICE data, including not having the scaling issue from #5508.

qview M1501447954C.vis.*spice.cub

Link the two images, zoom 1:1 or closer, and open the Tracking table and turn on the incidence column. Using the Find tool, click in various places around either image. Where the "halfspice" image has SPICE data (the incidence column has data, e.g. sample 900 line 5090), the two images will act properly linked. Where it does not (e.g. sample 900 line 5100), clicking will not align the images.
