Bug 1036787 sim card text on import and export contacts

If you moved argument tot he next line, please move the closing bracket as well. Instead of:
```
tempButton.setAttribute('data-l10n-args', JSON.stringify(
  {'number': 1, 'msisdn': 1}));
```
please do:
```
tempButton.setAttribute('data-l10n-args', JSON.stringify(
  {'number': 1, 'msisdn': 1}
));
```
or something similar, it will be easier to read when slosing bracket has the same indentation as opening bracket.
