client: fix result argument of wait

[drewdzzz]

The argument was completely broken - the commit fixes it.
Along the way, fixed a crash when a decoded future appeared in m_ReadyToDecode. See the commits for details.

Closes #112
Closes #124

Ignoring clang-format suggestions in order not to mess with the diff.
(I hope we'll do something about it sooner or later...)
