Trace installed packages even on yyoom error
Trace installed packages even on yyoom error

Since change Idc3823a4dfa3641122b7037fa3c6ba23b869d72f yyoom returns
non-zero exit status even if some packages were actually installed. So
in order to uninstall everything correctly we need to trace installed
packages even on yyoom errors.
