[BUG] Run tests with coverage with namespace - fails to detect coverage generated due to full name comparison

[JonnyPower]

Describe the bug
When running sfp apextests:trigger -u <org> -l RunAllTestsInPackage -c -n <dir> against a namespaced org, the cli fails to detect coverage as generated because

if (!testToBeTriggered.includes(test.apexClass.fullName)) {
    testClassesThatDonotContributedCoverage.push(test.apexClass.fullName);
    if (!testToBeTriggered.includes(test.apexClass.fullName))
        testToBeTriggered.push(test.apexClass.fullName);
}

is comparing the namespaced name against testToBeTriggered which is without namespace.

To Reproduce
Steps to reproduce the behavior:

1. Create test class in namespace org
2. Use SFP to run tests with coverage
3. Observe errors reported to stdout;

Tests to be executed: Foo

later;

Test Classes that were not able to contribute coverage: NAMESPACE.Foo

Expected behaviour
Should properly detect comparison with or without namespace - at risk of colliding coverage results if an unnamespaced class has the same name

Creating this issue with intention of submitting a PR shortly

Hey @JonnyPower even if you have just a draft of PR, I'm happy to take a look and finish it.
let me know ;)
