Problem:
When on the column mapping form (Step 6), clicking the 'Save Profile' button doesn't actually save the profile mapping.

Workaround:
Click the 'Next' button and save the profile on the next form (Step 7, Data preview). The profile will save properly.

To reproduce:
- start up the Import Toolkit
- load a .profile
- on Step 6, modify one of the mapping fields under 'source field or expression'
- open up the profile in a non-locking text editor (like textpad)
- click 'save profile'
- check the .profile file in the text editor, you'll see the new mapping value has not been saved.
- click the 'next' button to go to the 'data preview'
- click 'save profile'
- check the .profile file in the text editor. Your changes have been persisted.
