Print bootstrap url when browser cannot be opened

[sobolk]

Problem

There are legit cases when bootstrap url cannot be opened.
E.g.

• in headless environments
• if user does not have any app to open URL or lacks permissions to open it
• if browser crashes

Changes

Catch open errors, eat and log them (as debug logs), print url to the console.

Validation

added test
