Describe the bug

@jackmu95

On input of a b-form-input, the computed property hasFormatter throws a "Cannot read property 'name' of null" error when no formatter prop is provided, which results in this.formatter being null.
hasFormatter() { return this.formatter.name !== props.formatter.default.name }

EDIT: above code is in src/mixins/form-text.js

Steps to reproduce the bug

1. Go to a form that uses b-form-input
2. Open debugger
3. Type characters into the form field
4. See error in console
5. This appears to prevent a value from actually being set for the input

Expected behavior

User is able to enter a value and have the value persist on form submit
