Waited to see how many (if any) responses to this 'issue' ... none ... so I'll offer 2 cents ... in a 'nutshell', if it hurts, don't do it!
Suggest using a 'true to moodle life' senario in testing backups and restores. I imagine that Testers of any Moodle release do test backups and restores but not many (venturing a guess) if any would do the steps you've described here. While in theory, the backup/restores routines/code should allow any/every combination of settings, can see that conflicting decisions could cause a state of total confusion for Moodle thus rendering mis-leading debugs.
Table missing ... got ssh/shell access? Use mysql client on server and issue the following from the mysql> prompt using DB for Moodle:
mysql> use moodle36;
mysql> show tables like '%workshop%';
You should see:
+----------------------------------+
