freeze object before exploiting

[theoo]

in some strange case, when the given object has text fields and/or duplicated, the content of the object may be altered.
For instance, a string like "Address\nLocation\nCountry" should see its \n untouched but are converted into text:line-break/ by serenity.
Ensure this wont happen by freezing object, and/or find the relevant code to fix it.
