Fixes composer dependencies: Package phpunit/phpunit-mock-objects is abandoned
We cannot support v8 yet because of errors like:
Declaration of MailFunc::setUp() must be compatible with PHPUnit\Framework\TestCase::setUp(): void
It would require dropping PHP < 7.1 support.
Some clients encode quotes with name using base64/quoted-printable
encoding. Quotes were removed only for unencoded strings. Now also
encoded names are handled this way.
So, recipient/sender strings are displayed without quotes around
and e.g. saving to addressbook does not save these redundant quotes.
