* Refactored AssetsTransformer
Casted all ids to int, escaped all text values,
* Added warranty_expires attribute to Asset model
$asset->warranty_expires contains a Carbon object with the warranty
expiration date. Returns null when either purchase_date or
warranty_months are not set.
* Ignoring php-cs cache files
* Restored asset tests expectations
Work in progress - tests still fail
* API controller refactoring, fixed HTTP status codes in responses
* Restored $request->get - debugging
* Added further checks in ApiAssetsCest::updateAssetWithPatch
* Fixed undefined method
* Fixed initial underscore trimmed by str_slug
* CustomFieldTest now works where intl PHP extension is not installed
If a server doesn't have the intl php extension installed, the custom fields tests failed. Now the tests perform the same check done in the CustomField class.
