Including a . in the migration script regex

[travissouthard]

I ran the migration script last week and ran into a bit of trouble with the import statements.
Instead of changing the import lines to * from "react-ionicons" it skipped over the . at the end of the line and the from became react-ionicons.js

I locally changed line 25 in the migration file to include a . in the regex and that worked the second time.
Example:
line = line.replace(/(react-ionicons\/lib\/[a-zA-Z]*)/, 'react-ionicons')
became:
line = line.replace(/(react-ionicons\/lib\/[a-zA-Z.]*)/, 'react-ionicons')

And that solved the problem for us and helped the import lines match what's recommended in the documentation.
