Change subject: IMPALA-6824: Fix crash in
RuntimeProfile::EventSequence::AddNewerEvents()

IMPALA-6824: Fix crash in RuntimeProfile::EventSequence::AddNewerEvents()
When events_ is empty in runtime-profile-counters.h:347, events_.back()
is undefined. This can lead to a crash. The fix is to check for
events_.empty() before calling back().
This change adds a backend test to make sure that updating empty event
sequences doesn't crash.
