fix(clientSideScripts): bind-template directive shouldn't break bind locators

If you try to use the locator "by.binding" on a page that contains at least one "bind-template" directive, the following error will be raised: "UnknownError: angular.element(...).data(...).$binding[0] is undefined".

Ex:

HTML:
```html
...
<div>{{ myVar }}</div>
<div ng-bind-template="This directive will cause error: {{ myOtherVar }}"></div>
...
```

TEST:
```javascript
...
element(by.binding('myVar')).getText();
...
```
