Fixes multiple bugs that happen due to System.IO.IOException: There is not enough space on the disk

[DTraitor]

Fixes multiple bugs that happen when there is no storage left on the device and System.IO.IOException: There is not enough space on the disk. is thrown:

• DiskService not disposing itself in case of an exception
• DiskReader never being disposed if an exception was thrown during transaction disposal. It led to log stream never returning to the pool and never closing a handle to the log file resulting in RebuildService failing to rename the log file, as well as TransactionMonitor not disposing the rest of the transactions

Fixes #2286
Fixes #2614
Fixes #2615
