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 regressions correspondingly.
This patch is a follow-up to d23ee5d38ddc4317f431dd65df0c825c00cc968a.
Prior to the change in src/kudu/client/meta_cache.cc back-ported from
Kudu 1.14, the scenario crashed with SIGABRT when running, with stack
trace similar to the following (this one below captured at macOS):
