using translate-values breaks with a value that containing a quote in a filter with a target translate attribute set

Example:

``` html
<md-tooltip translate-child="(content)=UPDATED_AT.TOOLTIP"
                   translate-values="{
                      updatedAt: '{{ submission.updatedAt | date:'shortDate' }}'
                    }"></md-tooltip>
```

This causes an issue when the `translate-values` attribute is `$eval`'d in the linking function of the `translate-child` directive.
