[FieldFormatters] Use default values for URL formatter

[Tacklebox]

Summary

close #112238 (comment)

The default behavior when creating a URL formatter is to have the type set to link, But the link specific field wasn't being shown until the the type select box had a transition to the link select from a different type. This was caused because the default for the type field is link, but the formatter props still have type as undefined. I addressed the issue by calling format.getParamDefaults() and coalescing it with the provided type prop.

Checklist

• Unit or functional tests were updated or added to match the most common scenarios

The unit tests passed without modification. However, they also passed before, despite the snapshot including the html for the "Open in new tab" toggle. So I may be running them incorrectly.

For maintainers

• This was checked for breaking API changes and was labeled appropriately

Release Notes

Fix url formatter editor "Open in new tab" is hidden by default

Hey @Tacklebox, I have removed myself from review because I haven't touched this code in many years (since it was all in Angular) except for broad changes regarding ESLint and the like. I suspect that someone from @elastic/kibana-app-services will be able to give you a much more usable review.
