Add error/misconfiguration checks and fix undefined variables

User::fromVars in class ticket was the root. Eventually, in
DynamicForm::getDynamicFields(), isset($this->id) was used to detect
unsaved, new forms that have not been committed to the database; however,
the isset() method was not implemented for the ORM.

Some versions of PHP (5.3.6 on Windows at least) may corrupt `$ost` if it is
closed off as a global variable.

Fixes #917, #969

Allow direct access to tickets with email and num

Reviewed-By: Peter Rotich <peter@osticket.com>

Starting with osTicket 1.8.1, users must receive an email and follow a link
in the email to get access to the ticket. With this new option, the email
verification step can be avoided in osTicket 1.9, because access is now only
granted to exactly one ticket.

orm: Fix issues surrounding MySQL commands OoS

Reviewed-By: Peter Rotich <peter@osticket.com>

Several places in the code initialize a list of objects from the database
and only fetch one item. In certain instances (which seem almost like a race
condition), MySQL will feel like there are more records available in the
database and will complain with "Commands out of sync, you can't run the
command now".

This patch addresses the issue by utilizing the ::one() method of the
QuerySet where only one record is expected. The ::one() method is further
designed to fetch all one results (which satisfies the MySQL client library)
and return the first item.
