Fix PHPUnit deprecations

[franmomu]

Replaces #145, it adds @jmsche suggestion and requires explicitly doctrine/persistance.

I also added conflict with zendframework/zend-code < 3.3.1 because of zendframework/zend-code#158 and with doctrine/orm < 2.6.3 because of doctrine/orm#7325.

7x: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

I'm not sure from where this is coming from but looks easy to fix hopefully?

[jmsche]

The only place in the package's code where I found continue is there: https://github.com/theofidry/AliceDataFixtures/blob/master/src/Bridge/Symfony/DependencyInjection/Compiler/DeprecateServicesPass.php

Couldn't find any place using switch, so my guess is, it's located in vendors :/

[franmomu]

Let me try if it's doctrine/orm, if it's not, I'll take a look later today.
