[FIX] mail: chat window should remain folded on new message

If the chat window was initially folded and when a new message is received
the chat window automatically unfolds. it is annoying having a window that
pops up each time a new message is coming while having folded it once.
So, It should remain folded when a new message is received if the chat
window is already folded.
