Issue: Reenabling template rule causes template lint tests to fail
Since today I am getting failing linter tests in my test suite on templates that reenable the `bare-strings` rule.

This is causing failing tests:
```
{{!-- template-lint-disable bare-strings --}}
<i class="material-icons">folder_open</i>
{{!-- template-lint-enable bare-strings --}}
```

Exception:
```my-app/components/foo-bar/template.hbs
  -:-  error  Cannot read property 'indexOf' of undefined  undefined
@ 1 ms
Expected:     
true
Result:     
false

    at advance (http://localhost:7357/assets/test-support.js:3779:4)
```

This works:
```
{{!-- template-lint-disable bare-strings --}}
<i class="material-icons">folder_open</i>
```
Pull request description: Ensure deprecated rule names are properly migrated.
Prior to this change, deprecated rules specified in user specified config would not be included in the final config.

Fixes #417

-## no-attrs-in-components
-
-This rule prevents the usage of `attrs` property to access values passed to the component since all the values can be accessed directly from the from the template.
-
-For example, doing
-
-```components/templates/layout.hbs
-{{attr.foo}}
-```
-is bad. The correct way would be to directly consume `foo` in the template like,
-
-```components/templates/layout.hbs
-{{foo}}
-```
-
-or if you using Ember 3.1 and above,
-
-```components/templates/layout.hbs
-{{@foo}}
-```
-
-
-The following values are valid configuration:
-
-  * boolean -- `true` for enabled / `false` for disabled
