[configuration] Fix option deletion issue.

[racostas]

Brief summary of changes

The handler in configuration/jsx/configuration_helper.js was not properly taken the option to be deleted since the fields not always have necessary to be of SELECT type (they could be also text for example).
Now it should take the appropriate option to be deleted.

Testing instructions (if applicable)

1. Please go to configuration module MainMenu->Admin->Configuration

2. Go to one of the "Tabs" that allow multiselect (for example MINC to BIDS Converter Tool Options )

3. Create some options and try to delete they after
   

4. Test Confirming and Canceling

5. The field should be deleted under confirmation.

6. Please test also with "other data type" (for example instruments in Study tab)
