Fix of the issue that after entering messages
app, opening one of the threads and returning
to main messages app window, new messages in
this thread were automatically marked as read.
Fix of the issue that entering 'Options' menu
after forwarding message caused the content
of the message to be pasted into message
field in thread view.
Minor cleanup.
Fixed case, when there's only one thread unread and
there's no info about the thread, only a generic message
Tests are deleted because the fix would require rewritting ALL
of those tests - those will be written with new implementation
of notification table
1. Prepare Pure and Bell specific `Application`
classes and add them to `app` target:
- `products/BellHybrid/apps/Application.cpp`
- `products/PurePhone/apps/Application.cpp`
2. Update `CMakeLists.txt` files.
3. Move `ApplicationBell` implementation to Bell-specific
`Application` class and remove `ApplicationBell` files.
4. Change Bell apps parent classes from `ApplicationBell`
to Bell-specific `Application` class.
5. Rename `Application` to `ApplicationCommon` in the rest of the files.
