Bug 37607: Only default to manual form if we are editing

This patch fixes an issue where the form to add a provder would automatically default to the manual form. This patch prevents this behaviour and restores the intended functionality.

Test plan:
1) Don't apply the patch
2) In ERM, click to add a new provider
3) Type something in the provider name search box
4) The input will change from a select to a text input and the button next to it will now say "Create from registry"
5) Apply patch
6) Yarn build and hard refresh the browser
7) Repeat steps 1-3, the form should work as intended and return results in the select box
