Che-theia doesn't inform che-master about activity in workspace when https with self-signed cert is used

Describe the bug

Che-theia doesn’t inform che-master about activity in the workspace when https with self-signed cert is used. I assume the reason is that https://github.com/eclipse/che-theia/blob/master/extensions/eclipse-che-theia-activity-tracker/src/node/activity-tracker-service.ts#L68-L90 is not covering usecase with a self-signed cert.

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

1. Setup Che chectl server:start --platform=crc --installer=operator --tls --self-signed-cert
2. Start workspace.
3. Workspace would be stopped with default timeout no matter what you are doing inside of it.

Expected behavior

Che-theia should send activity reports to che-master
