Tim Abbott 804f473214 message_list: Extract visibly_empty helper method.
This function will allow us to adjust the codebase to write what it
means semantically -- whether a check is for the message list being
visibly empty, or completely empty.

In this commit, we leave the .empty() method incorrect, because
several other adjustments need to be made atomically with fixing it.

// Important note on these tests:
//
// The way the Zulip hotkey tests work is as follows. First, we set
// up various contexts by monkey-patching the various hotkeys exports
// functions (like overlays.settings_open). Within that context, to
// test whether a given key (e.g. `x`) results in a specific function
// (e.g. `ui.foo()`), we fail to import any modules other than
// hotkey.js so that accessing them will result in a ReferenceError.
//
// Then we create a stub `ui.foo`, and call the hotkey function. If
// it calls any external module other than `ui.foo`, it'll crash.
// Future work includes making sure it actually does call `ui.foo()`.
// Since all the tests here are based on narrow starting with all_messages.
// We set our default narrow to all messages here.
