installing plugins will reset UI to default and not reflect already present changes made

## Describe the bug
* UI changes reflected after "make build"
* UI changes lost after "./answer build --with example-plugin"

A clear and concise description of what the bug is.

### To Reproduce

Steps to reproduce the behavior:

1. ./answer init -C answer-data/
2. ./answer run -C answer-data/ => UI changes still present ✅ This is what we want.
3. Install plugin via cmd: ./answer build --with github.com/apache/incubator-answer-plugins/search-elasticsearch --with github.com/apache/incubator-answer-plugins/cache-redis
4. Restart app: ./answer run -C answer-data/ => Plugins got installed, but UI changes lost and set to default. 💥

Installing plugins will reset UI to default.

### Expected behavior

Installing plugins should not reset UI to default.

### Platform

Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
Codename: jammy

answer version 1.3.5
revision: 3ce69256

使用 ./answer init -C answer-data/、./answer run -C answer-data/ 以及包含列出的 search-elasticsearch 和 cache-redis 插件的 ./answer build --with 复现该问题。跟踪还原 UI 更改所涉及的构建和启动路径，然后验证自定义 UI 在插件安装和重启后仍然保留。
