Details:

(Sorry, title could be better, suggestions?)

When trying to uninstall a package that no other installed package depends on
while there are missing dependencies elsewhere, pkg.m emits an error message
and stops:

>> pkg uninstall octproj
error: the following dependencies where unsatisfied:
   geometry needs matgeom >= 1.0.0


Indeed geometry-4.0.0 needs matgeom (that was indeed missing), but none of
them depends on octproj. IMO octproj could safely be uninstalled.

Expected result (in this case):
The error message had better be a warning, and octproj should be uninstalled.

The relevant code isn't easy to follow, but if confirmed I'll try to come up
with a cset.
