one-way-input-mask with custom mask does not work after upgrade

Hi,
following setup worked properly with ember-inputmask versions < 0.7
```javascript
//mask-definition
import Inputmask from 'inputmask';

export function initialize(/* application */) {
Inputmask.extendAliases({
euro: {
suffix: " €",
groupSeparator: ".",
radixPoint: ",",
alias: "numeric",
placeholder: "0",
autoGroup: !0,
digits: 2,
digitsOptional: !1,
clearMaskOnLostFocus: !1,
autoUnmask: true,
unmaskAsNumber: true
}
});
}

export default {
initialize
};

```
```javascript
{{one-way-input-mask value=12.58 mask="euro"}}
```
Since ember-inputmask > 0.7, the same output results in following output:
The given value (12.58) is multiplicated by 100. Why?
Can you help me?

thank you

Start by reproducing the snippet from the issue in ember-inputmask versions before and after 0.7, using a custom Inputmask alias named euro and {{one-way-input-mask value=12.58 mask="euro"}}. Then compare the upgrade behavior around custom aliases and numeric unmasking. Done means the masked value no longer appears multiplied by 100 for this case.
