Android v1.8.1

[Revertron]

Connectivity improvement

• Fixed tracker-resolver. Added a timeout code to properly process timeouts.
  It was possible in some situations that sending messages will be stuck in unresolvable state, thinking that it is already connecting to a contact, but not doing it.
• Fixed some closeable leaks in storage. Properly closing statements and cursors in SQLite is a way to success :)
