Move SectionEndInfo into sectionEnded call in SECTION's destructor

When running `./tests/SelfTest -o /dev/null`, this saves 1272
allocations (437439 -> 437167). In general, this saves multiple
allocations per end of an entered `SECTION`, if the section name
was too long for SSO, because `RunContext::sectionEnded` can then
move the section's name further down the callstack.
