Fix compatibility with latest @vue/composition-api

This release brings the composition-api features inline with the latest breaking changes to the @vue/composition-api package. The breaking change is in the useFind and useGet utilities. The lazy option has been replaced by the immediate option.

Migration

• If you are manually using lazy: true anywhere, replace it with immediate: false.
• Remember that the change to composition-api requires you to set { immediate: true } in the options, where that used to be the default.
