Fixed tests by changing their order

The reason behind is that Laravel 6.18.35 & 7.24.0
introduced a security improvement that prevents from
mass assigning non-db fields to an Eloquent model.

The implementation is holding a reference to the list
of the table fields in the newly introduced
`guardableColumns` static property. It gets populated
with the fields from the db for the first time a mass
assignment happens on a model.

In our tests, we add fields to the cart_items table
during testing. If we hit the model first with the
original amount of fields, the second call - having the
new fields in the underlying table - won't repopulate
the `guardableColumns` static property - for obvious
reasons. However, there's no facility to reset this
list, therefore we can't reboot this property of a
model within a single run of a PHP process (namely tests).

A dirty fix was to move the test with the extended
number of columns ahead, thus those columns will be
populated. Cheap fix, but actually in a real application
it's not the case, it's only causing problems with
testing. Thus, we get away with it. We have more
important stuff to take care of ;)
