/**
 * Returns the original value of an object member, that is, the last committed value.
 * 
 * This is useful if you want to compare the actual value with the last stored value. 
 * - item : the object of which you want to inspect a member
 * - member: the member to retrieve the previous value from. Note that for references, the module name needs to be included.
 * 
 * The function is applicable for non-String members as well, but always returns a String representation of the previous value.
