Selected data lost when adding new rows via ajax

[jmfederico]

Hello

In 1.4 series, data is lost from ajax enables fields which had no initial data on page load when re-triggering "init-autocomplete".

To reproduce:

1. Load a page with ajax enabled fields.
2. Select data on at least one field
3. Trigger "init-autocomplete" (can be via console)
4. Data will be lost

Symptoms:

• If field had initial data on load, it will be re-set to what it had.
• If field was empty, it will be set to empty.

This is a problem when using inline formsets with ajax enabled fields, when the user clicks the add-more rows link/button.

Seems that it is triggered because on the new reset function, it checks for initial data but not for current data.
