Small improvements

[zbrag]

Hey,

we're currently using this implementation ourself, and we ran into some small problems which we fixed in this pullrequest

1. Is was impossible to use PSR/log of (in this case) whmcs, bu allowing version 1 and 2 as well, we can use is even with older php versions. The functionality doesn't change with this patch, but it allows to use even PHP 7.4 with the api (which is kinda supported by some linux distros)
2. Getting a quote from the domain api was not processed correctly. It now works as advertised
3. The account credit code failed when we returned more than one currency. This has also been fixed

I hope you are able to merge this pullrequest without any problems.

@zbrag The only thing which stops us from merging this PR is the failing CI.
Can you fix, commit and push the php-cs issues in src/Api/ProvidersApi.php and in src/Api/DomainsApi.php, then we can merge this PR.

Sorry about that, it seems the composer.lock I had referenced some old version of the codestyle. I hope this fixes the problems :)
