This commit refactors the category id normalization of param-input to
use `Category.asyncFindBySlugPath`.
Now, the category id input will use an async query when the
default/initial value is category slug.

The `onSubmit` hook will only be triggered when the form is valid, so we
need to clear the contents of `serializedData` in advance in `submit`.
Otherwise, it may not throw a validation error.
