When the user entered a number beyond the stock level, the browser was
correcting that to the max number which is very helpful. But Angular was
setting the model to undefined which removes the item from the cart.
Deactivating Angular's max behaviour let's us set the value ourselves
which is then used in the cart.
If the user entered an invalid quantity, Angular set the model to
undefined and we removed the input field to show the add button. That
makes it impossible for a user to see what the maximum quantity to enter
would be. For example:
- The variant has a stock level of 5.
- The user enters 7.
- Angular sets it to undefined.
- The input field disappears.
- The user is startled and doesn't know how to proceed.
But now we hide the input only if it's deliberately set to zero.
The user can now type anything into the quantity field and some of it
may not be valid. These safe guards ensure that the buttons still work
even if the quantity is undefined or out of range.
Angular guards against the value being out of range but that has other
side-effects. We want to be able to de-activate some of Angular's
behaviour.
It's simpler if there is just one place to add a new product. Closes#6650
This removes the 'creating directly from the new product path' test scenario because we have another 'assigning important attributes' scenario above which provides enough coverage.
We're in Rails 4.2 so we can remove it. This gets rid of the following
message when running tests:
```
DEPRECATION WARNING: Suppressing Selenium deprecation warnings is not needed any more. (called from block in <top (required)> at /usr/src/app/spec/spec_helper.rb:214)
```
Devise has been complaining about this for a while in the test suite:
```
[Devise] including `Devise::TestHelpers` is deprecated and will be removed from Devise.
For controller tests, please include `Devise::Test::ControllerHelpers` instead.
```

Spree used to give you more options to configure ActionMailer but our
setup is much simpler. We can remove unused code.
The removed option was never used by OFN and defaulted to true. We don't
need a database migration because the value isn't set in the database.
