Alpha 1.0.10: unpinning converted chat on demand.

Browse Source 
If we want to pin a chat and we have reached the limit we now check
for a deactivated (converted to supergroup) chat that is pinned and
is not in the chats list and just silently unpin it if it is found.

Also possible UB fix for a waveform encoding and decoding.
