Make compatible with the new syntax without configure the templating

[Sentence]

The bundle isn't compatible with Symfony 3.4+ or 4+.

1st method, the configuration (without apply @Richard87's patch, #35, but also need to remove the hardcoding dependency):

a) We need to configure the old templating in the config.yml, now the bundle can use the templating service

# app/config/config.yml
framework:
    templating:
        engines: ['twig']

b) Override the template in config.yml

apy_breadcrumb_trail:
    template: '@APYBreadcrumbTrail/breadcrumbtrail.html.twig'

2nd method, the bundle patch to v2 with this pull request.
