[PITR-YSQL-Tablet Splitting] After restore, select data from table throws Illegal state error

[Arjun-yb]

DB Version: 2.8.0.0-b2

Steps:

1. Create database and table(employees)
2. Create snapshot schedule
3. Collect time(t1) and number of tablets(n).
4. Start workload and observe the tablet splitting count increases(>n)
5. Stop the workload and restore to the time(t1) which is collected at step:3
6. Then select the data from the table(employees)

demo=# select count(*) from employees;
ERROR:  Illegal state: [Illegal state (yb/client/meta_cache.cc:909): GetTableLocations { table_name: demo.employees, table_id: 00004000000030008000000000004001, partition_start_key: Pgsql Hash, partition_list_version: 66, request_no: 2, num_attempts: 1 } failed: Wrong order or overlaps in partitions]

Observations:

1. Tablet count increases after running workload.
2. If user restores data and select data from table, it throws above error(if the tablets count is increases in between collect time and restore time)
3. If the tablets count is same(in between collect time and restore time) restore works fine and user can able to select data from table.
