Do not reload smart dial database twice in DialtactsActivity.

In fe57f36d different logic was
introduced to reload the smart dial DB when the locale changes. This
added a duplicate call to update the smart dial db if the locale has not
changed. Remove the duplicate call that existed before this patch.
