Fix VB365 collector against a real server's object model

Checked with Get-Vb365CollectorDiagnostics.ps1 output from a VB365 8.4
server (GDC-VEEAM-04, 11 organizations, Windows PowerShell 5.1). Times
(session CreationTime/EndTime, job NextRun) are local, and property
names matched. Two fixes:

- Session log items carry their status as a Title prefix ("[Warning]
  ...") with no separate status property. Match on the prefix and strip
  it, instead of matching words in the text, which would have pulled in
  lines like "[Success] Processing site: .../error-reports"
- Retries are separate sessions (MainSessionId -> the retried session,
  which has JobWillBeRetried = True). Mark them in details (retry_of,
  will_retry) and say "Veeam will retry this job." on a pending retry

Mock rebuilt on the real shapes, including a warning + retry pair.
