FLOOD_WAIT exception while downloading media is uncaught, and causes the program to exit #84

While downloading messages normally, FLOOD_WAIT exceptions are caught and followed, however while downloading media a FLOOD_WAIT causes the whole program to exit as the exception remains uncaught.

This error makes it impossible for me to download a full backup because the program always crashes at the same file.

----- EXIT -----

For me at least, after many tries (ten or so) I managed to get through every file. One thing that helped was waiting a long time (an hour) before trying again. In your case, telegram is asking you to wait for 852 seconds (FLOOD_WAIT_852) so if you try again before that it will probably fail in the same way.

I waited over a day once. It always crashes at 30300 files, just like you can see in my log. Even pausing the program with CTRL+Z and resuming much later doesn't change anything.

@Rapti I have fixed this issue in pull request #87

If / when it's merged, the issue will be fixed in this main repo, until then you could compile and run it yourself from my fork https://github.com/leijurv/telegram_backup

Alternatively, I have compiled my fork into a .jar which is available for download here.
