This PR adds a little shorcut for tags without any attributes. There are increasingly more name-only tags in Symfony and having to do `{ name: twig.extension }` for these seems way too verbose to me.
**Before**
```yaml
services:
app.twig_extension:
class: AppBundle\Twig\AppExtension
tags:
- { name: twig.extension }
```
**After**
```yaml
services:
app.twig_extension:
class: AppBundle\Twig\AppExtension
tags: [twig.extension]
# or
# - twig.extension
```
This of course means we introduce a new format to achieve the same goal. I believe this isn't a big problem as the decision is distinctive and simple: If you configure tag attributes, use the long format, otherwise use the short format.
Backwards compatibility
---
In this PR, an exception was removed to allow this new shortcut format. The BC promise doesn't cover exceptions and I think removing the exception here should cause anything to break:
* Applications shouldn't rely on exceptions
* If code was triggering this exception before, it would not cause any behaviour change after this PR: The service just retrieves an unused tag, which is simply ignored by the container.
