#5715 Fix id token fetch for exception reports

[sosnovsky]

This PR fixes id token fetch for sending error reports from content script.

+ replaces { line: 0, col: 0 } with { line: 1, col: 1} for reports with unknown error location (as backend expects positive number, and throws error when line or col is 0)
