KUDU-3254 fix bug in meta-cache exposed by KUDU-1802
This patch fixes an issue resulting in a SIGABRT crash in Kudu client
when working with stale scan tokens which contain information about
tablet locations for a table (see KUDU-1802) whose range partition
was dropped. The patch also adds a test scenario reproducing the crash;
now it passes and can catch future regressions.
This patch is a follow-up to d23ee5d38ddc4317f431dd65df0c825c00cc968a.
Prior the change in src/kudu/client/meta_cache.cc was back-ported from
Kudu 1.14 as part of this fix, the scenario crashed with SIGABRT when
running with the stack trace similar to the following (this one below
was captured on macOS):
