Describe the bug

If the option autojump is set to true and there are no symbols present in the current buffer that Aerial can display it errors as follows:

Press ENTER or type command to continue

After pressing Enter twice the Aerial windows opens and shows the expected "No symbols" placeholder.

Steps To Reproduce

1. Open the Aerial config below in Neovim with Aerial installed and configured with this config (autojump = true).
2. Run the :AerialOpen command.

Expected Behavior

It should open empty, displaying the placeholder "No symbols" without causing an error to be displayed by Neovim.

Minimal example file

require("aerial").setup({
        layout = {
                max_width = { 40, 0.2 },
                min_width = 10,

                -- Enum: prefer_right, prefer_left, right, left, float
                default_direction = "prefer_left",

                placement = "window",
        },

        attach_mode = "window",

        -- List of enum values that configure when to auto-close the aerial window
        --   unfocus       - close aerial when you leave the original source window
        --   switch_buffer - close aerial when you change buffers in the source window
        --   unsupported   - close aerial when attaching to a buffer that has no symbol source
        close_automatic_events = { "unfocus", "switch-buffer", "unsupported" },


        -- A list of all symbols to display. Set to false to display all symbols.
        -- This can be a filetype map (see :help aerial-filetype-map)
        -- To see all available values, see :help SymbolKind
        filter_kind = {
                "Class",
                "Constructor",
                "Enum",
                "Function",
                "Interface",
                "Module",
                "Method",
                "Struct",
        },

        highlight_on_jump = 2000,
        autojump = true,
        close_on_select = true,
        show_guides = true,
})
