MDEV-22941 Assertion `idx < array.elements' failed in Dynamic_array<st_mysql_const_lex_string*>::at
The code in fill_schema_schemata() did not take into account that
make_db_list() can leave empty db_names if the requested database
name was too long, so the call for db_names.at(0) crashed on assert.
- Moving the code testing if the database directory exists
into a separate function verify_database_directory_exists()
- Modifying the test to check if db_names is not empty
