[RFC] Allow to output more verbose error messages in contao:resize-images command

[qzminski]

Together with @Toflar we had a hard time debugging why the contao:resize-images command stopped at some point and did not want to continue. The error message was quite unclear especially that the requested file existed:

6/77b26349-9084f1ba.jpg......... failed
Unable to open image /var/www/vhosts/domain.tld/httpdocs/releases/233/assets/images/../../var/pim-images/77b26349.jpg

So we decided to introduce an option that allows to output more verbose error message simply by executing command in verbose mode contao:resize-images -v:

f/8ac5c4ec-213df40b.jpg.............. failed

Thank you @qzminski.

This should have gone into the master branch, because FlattenException::getAsString() does not exist in Symfony 4.2. 😞

[Toflar]

I don't think so, no. It's a bugfix because of nonsense output. So it needs to be fixed in 4.8.
However, maybe we need some method_exists() check.

See #917.
