What happened?

Calling Craft::error() appears to have no effect in Craft 5.0.5.

Steps to reproduce

1. Enable devMode.
2. In a custom module, call Craft::error('Test error') and Craft::info('Test info') in the init() method.
3. Visit the site.
4. Open the web-****-**-**.log file.

Expected behavior

Both test messages should be written to the log file.

[web.ERROR] [application] Test error
[web.INFO] [application] Test info

Actual behaviour

Only the info message is written to the log file.

[web.INFO] [application] Test info
