Move tests/phpunit/Bolt tests into /tests

[grasmash]

Move tests from template/tests/phpunit/Bolt and template/tests/phpunit/src/TestBase.php to tests/phpunit and ensure that they continue to be executed by template/.travis.yml and pass.

@grasmash - I'll pick this up, but I do not appear to have access to assign myself.

@grasmash - After setting up a blt-project directory next to blt as outlined in CONTRIBUTING.md, I am able to get all the phpunit tests to pass with the exception of the drush test. However, I'm not able to actually install drupal using any of the blt commands.

My setup:
Follow steps in CONTRIBUTING.md:

cp -R blt/blt-project .
cd blt-project
git init
composer install
blt init
blt configure
composer update

Follow steps in INSTALL.md which follow blt init/blt configure/composer update. I configured DrupalVM as I normally would, but I left all the defaults for configuration of project name, etc.

blt vm:init
vagrant up
blt local:setup

The drush site-install command results in the following error:

blt > setup:drupal:install:

Notice drush root is configured to be my local path, not the Drupal VM path. However, it does correctly find the alias.

If I set drush.root in project.local.yml to an empty string, the command now cannot find the alias:
