Fix trusted app configs getting cleared issue

[ImalshaG]

Purpose

If FIDO trusted apps feature is disabled, set each property inside trusted app metadata as empty and set isFIDOtrusted app attribute to false instead of setting the whole trusted app metadata object to null.

This is done to resolve the issue of trusted app data getting cleared when the General or protocol tab is updated. This is happening because during such patch calls, the rest of the application advanced configuration attributes will be set as null except for the needed attribute, and therefore the trusted app metadata will be removed from the DB.
