Search box part 4

[RomaricMourgues]

Bugs

• results that matches the most of input words should comes first for channels
• Show quickly "private channel" for channels that are not private
• Some channels shows "you cannot access this content" for some private channels or direct channels (?)
• When leaving channel this is not updated automatically for "isChannelMember" and search box
• Space in channel context
• Closed modal still has mouse interaction from @rezk2ll
• Fix badge number of results (medias should keep showing even if no thumbnail)
• Show channels in All in rows instead on column when searching
• Show attachment with messages result (as we search in message attachment names too)
• Small modal should be vertically stable (min Height + top static pos ?)
• Download banner fixes
• if not logged in do not try to open desktop app
• add the try_desktop=1 to all shared links, only open the desktop app if no path or query string contain try_desktop

Backend

• The recent channels endpoint doesn't return not joined channels
• Add users to channels object returned by message object in search
• Recents should use channel context
