schemeshard: fix enable_alter_database_create_hive_first mode

[ijon]

Storage pools duplication (in memory only) happened at the first database alter (first alter is actually constructs the database) causes StatusInvalidParameter errors for the next alters if they repeat storage pools specification. Ydbcp does exactly that and so databases created via ydbcp are displayed in the webui as having CONFIGURING state instead of RUNNING.

Databases stuck in that state are actually fully functional, but still are not being able to execute some alters until root schemeshard is rebooted.

KIKIMR-10367
YDBOPS-7628

Changelog entry

Fix alter-extsubdomain behaviour that could prevent some database alters from executing when enable_alter_database_create_hive_first feature flag is enabled.
