I use another ID, ZeroMe ask me to create profile again.

### Step 1: Please describe your environment

* ZeroNet version: rev3550
* Operating system: windows & Android
* Web browser: windows firefox61 & Android Chrome
* Tor status: not available
* Opened port: no

### Step 2: Describe the problem:
When I copy another ZeroID to /data, restart ZeroNet, go to ZeroMe, it ask me to create profile again, but I have created profile before. if I create profile again, all my posts data are losed. I rebuilt ZeroMe.db is NOT work.

通过将另一个 ZeroID 复制到 /data、重启 ZeroNet 并打开 ZeroMe 来复现问题。首先检查 ZeroMe 在加载现有配置文件时如何使用 ZeroMe.db；据报告，重建该数据库没有帮助。完成的标准是：更改 ID 后现有配置文件能够加载，并且之前创建的帖子仍然可用。
