This fixes:
```
DEPRECATION WARNING: Passing an argument to force an association to
reload is now deprecated and will be removed in Rails 5.1. Please call
`reload` on the result collection proxy instead. (called from
can_own_more_enterprises? at /usr/src/app/app/models/spree/user.rb:112)
```
This method in particular gets called a lot of times so it'll have it's
cost in performance.
