ISQL: presence of credentials ('-user SYSDBA -pas masterkey') causes "Different logins in connect and attach packets - client library error" if new DB is created by privileged user

[pavel-zotov]

Consider following script:

set echo on;
set bail on;
shell if exist C:\temp\tmp4test.fdb del C:\temp\tmp4test.fdb;
show version;
create or alter user tmp_boss password '123';
commit;
grant create database to user tmp_boss;
show users;
commit;

create database 'localhost:C:\temp\tmp4test.fdb' user tmp_boss password '123';
drop database;
quit;

Run it:
C:\FB\60SS\isql /:employee -i C:\FBTESTING\qa\firebird-qa\tests\bugs\tmp1.sql -user sysdba -pas masterkey

Output since 6.0.0.570 will be:

set bail on;
shell if exist C:\temp\tmp4test.fdb del C:\temp\tmp4test.fdb;
show version;
