[FIX] sms: save the record before opening the sms wizard

**Issue:**

- Open crm.
- Open a lead.
- Input a number in the phone field.
- Click everywhere for the input to be recognized.
- Click the sms button that appears when hovering over the phone
  field.
- BUG1: The shown dialog doesn't have the inputted phone number.
- BUG2: When closing the dialog, any changes made in the form
  before clicking the sms button are lost.

**Solution:**

Make sure the changes are saved before calling the action that
shows the wizard.

After this fix:
- The phone number input in the form is now used in the
  wizard.
- When closing the wizard, the "unsaved" changes are kept.
