Ensure internal_vproblem always prints the message

Ensure internal_vproblem always prints the message

While working on internal_vproblem I noticed that the error/warning
message is suppressed if problem->should_quit is internal_problem_yes
or internal_problem_no.  This behaviour seems wrong.  This commit
modifies internal_vproblem to emit the message regardless of the
user's settings.
