PHP7 tests not running

[CupOfTea696]

Tests haven't been running on PHP7 in Travis since b787af1, Build #11. Not entirely sure why. I can run tests on my local machine in PHP7.

Aditionally, tests are failing in PHP7 due to a change (#25240) introduced in Laravel 5.5.44 and 5.6.34.

These are the errors:

1) ScopedNodeTest::testDescendants
Failed asserting that 0 matches expected 1.

./tests/ScopedNodeTest.php:110

2) ScopedNodeTest::testAncestors
Failed asserting that 0 matches expected 1.

./tests/ScopedNodeTest.php:127
