Issue number: N/A

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

`@ionic/angular-server` has a dependency on `@ionic/core` not
`@ionic/angular` (see
1f06be4a31/packages/angular-server/package.json).
As a result, once `@ionic/core` is built there is no reason for
`@ionic/angular-server` to also wait for `@ionic/angular` to build
before it can build.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- `@ionic/angular-server` now waits for `@ionic/core` to build instead
of `@ionic/angular`

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
