Since version 2.0.10 session_regenerate_id() error

[sergiobelya]

What steps will reproduce the problem?

1. composer update yiisoft/yii2-debug
2. login (may be login before composer update)
3. wait for session timeout expired (or set session['timeout'] to small value in config)
4. update page
5. pay attention error/exception "session_regenerate_id(): Session write failed. ID: user" on debug mode https://prnt.sc/j5zr17
6. update page
7. pay attention auto logout (while authorization with cookies is enabled, because on step 5 thrown Exception)

What's expected?

Exception after session expired not present and auto logout not execute on debug mode.

What do you get instead?

Error/exception "session_regenerate_id(): Session write failed. ID: user" present on debug mode.
Auto logout execute after exception.

I guess session_start() is run too early in “UserPanel”
