Discussion
----------

Allow PHP 7.2 & 7.3 and PHPUnit 6

Switch to PHPUnit 6 `TestCase::expectException()` & `TestCase::expectExceptionMessage()` from PHPUnit 4 `TestCase::setExpectedException()`

Add PHP 7.2 & 7.3 (nightly) to Travis matrix with temporary workarounds for disable `xdebug` & `./vendor/bin/php-cs-fixer` until 7.3 full support
