Unread counter never gets updated to a smaller number if blinking is off

OS: Windows 10 64-bit, possibly a fairly recent version of Linux Mint as well Birdtray version: 1.8.1 Thunderbird version: 68.8.0 (32-bit) Birdtray origin: Installer Qt version: NA

Description If Blinking speed is set to Off, the unread counter on the icon never gets updated to a smaller number e.g. when reading emails.

Expected behavior If Blinking speed is set to Off, the unread counter on the icon never gets updated when the real number becomes either smaller or greater than shown on the icon.

To Reproduce

1. Receive an email.
2. Take a look at the unread counter on the icon.
3. Read the email received at step 1.
4. Take a look at the unread counter on the icon.

Additional context Seems to be reproducible on Windows for sure. On Linux Mint, the number never seem to get smaller without restarting Birdtray, but I have not verified whether setting Blinking speed to a value other than Off actually makes it update. Of course I suspect it's the same as on Windows.

Judging by a quick look at other issues, https://github.com/gyunaev/birdtray/issues/317 looks like it might have the same root cause.

I have just tested this on Windows and verified it in the code and I can confirm that the updating of the counter is independent of the Blinking speed setting.

It might have seen like the two are connected, because every time the settings are saved, he unread counter is updated. Additionally, on Windows Birdtray is currently not really able to detect the changes immediately using the file watchers, because Thunderbird is not closing the mail account files after changing them, so the file watchers don't trigger. The most reliable way to see the updates to the unread counter on Windows currently is the force unread timer in the advanced settings tab.

If you find an instance, where you see in the log window that Birdtray parses a new unread counter, but doesn't update the tray icon, please reopen this issue or open a new one.
