<!--

**Apache Airflow version**: latest

**Environment**: Linux

- **Cloud provider or hardware configuration**:
- **OS** (e.g. from /etc/os-release):
- **Kernel** (e.g. `uname -a`):
- **Install tools**:
- **Others**:

**What happened**:
Unauthenticated access with RBAC to URL has_dag_access results lose redirection

**What you expected to happen**:
Redirection maintained, user can login and redirected to proper page

Missing next URL parameter

**How to reproduce it**:
Setup airflow with RBAC
Have a user who hasn't log in access a URL that uses decorator has_dag_access, i.e:
  http://localhost/graph?dag_id=dag_id
User will be sent to login page, (note the next= argument that required to redirect to original page is gone)
Login properly, user then will be sent to bad page


If this is a UI bug, please provide a screenshot of the bug or a link to a youtube video of the bug in action
