queryPrepared() returns the wrong state if in silent mode

[PascalTurbo]

Describe the bug

When running installer of membership fee plugin on a fresh Admidio installation that uses PostgreSQL , installation is running in an endless loop because the table "_plugin_preferences" is never created.

System (please complete the following information):

• Admidio-Version 4.3 latest
• PHP 8.4.2
• Database PostgreSQL

Bug analysis:

Membership fee expects the call to queryPrepared() to return false, if the table doesn't exist.

I've added a PR to solve the issue for 4.3.
If this fits I'll check for master, if the same issue occurs.

Thanks for resolving this error.
I made a cherry pick for the master and small improvements there. So bug is also resolved in master.
