Improve phpunit-tests-exist-rule

Migrated issue

Reported by: webflo

Related to !231 (merged)

Problem/Motivation

phpunit tests did not run for the domain module. Domain module contains multiple modules and has no phpunit tests on the repo root. We should improve the default configuration for modules (git-repos) with multiple modules (or sub-modules).

Steps to reproduce

Proposed resolution

Relax the globbing pattern in phpunit-tests-exist-rule

Remaining tasks

User interface changes

API changes

Data model changes
