[Proposal] Update dompdf/dompdf to 0.8.0 to fix PDF Invoice ErrorException using PHP 7.1

[waitem]

Laravel Spark v4.0.5 (using Laravel/Cashier 7.0.6) produces an error exception when trying to display an team invoice:

ErrorException in Table.php line 577:

Cashier currently requires 0.7.x of dompdf/dompdf.

The problem appears to be resolved with v0.8.0 of dompdf/dompdf. See: github issue

This proposal is to update the version number of dompdf/dompdf in cashier's composer.json to ^0.8.0

@waitem Did you find a way to force install dompdf 0.8? Running into the same issue at the moment.

@faustbrian Sorry, no. Beyond my skill level I'm afraid! Hoping that either a) we get a new version of laravel/cashier, or b) someone else can show how to temporarily override the dompdf/dompdf version in laravel/cashier's composer.json until the new version comes out.

Just ended up cloning cashier locally and loading it that way instead of from packagist

OK, I have seen that a fix has been made to the 7.0 branch a few days ago: commit

Until a new 7.0.x release is made, I was able to resolve this issue by making the following changes to my composer.json:

    "require": {
         ...
          "laravel/cashier": "7.0.x@dev",
          ...
    }
   ...
    "repositories": [
        {
            "type": "git",
            "url": "https://github.com/laravel/cashier.git"
        }
    ]

and then running composer update
