BUG - Running cds commands changes the html5 commands affecting build step

[longieirl]

Description

Step1. Generate a CAP project using a managed approuter;

cds init managedAppCAPProject && cd  managedAppCAPProject && npm install && cds add tiny-sample && cds add hana && cds add mta && cds add xsuaa && cds add connectivity && cds add destination && cds add html5-repo && cds build --for hana && cp gen/db/package.json db && npm i

Step2. Append a LROP UI page using the SAP Fiori tools wizard.

Step3. Add MTX to existing project;

cds add multitenancy
cds add extensibility

Step4. Build mta archive;

yarn build

The build step fails and there are now extra commands in the html5 module, for example;

Before;

  - name: ui5mtxsql
    type: html5
    path: app/ui5-mtx-sql
    build-parameters:
      build-result: dist
      builder: custom
      commands:
        - npm install --registry=https://registry.npmjs.org/
        - npm run build:cf
      supported-platforms:
        []

After:

  - name: ui5mtxsql
    type: html5
    path: app/ui5-mtx-sql
    build-parameters:
      build-result: dist
      builder: custom
      commands:
        - npm install
        - npm run build:cf
        - npm ci
        - npm run build
      supported-platforms:
        []

Steps to Reproduce

As shown above

Expected results

When running any of the cds commands, the html5 commands shouldnt change or impact the UI5 app already appended.

Actual results

Extra commands are added and impacts the build step which can fail and/or take double the time to build due to the duplication of steps
