Doesn't find backend if ...

[rgnkn]

Describe the bug
I use packer for plugin management. Everything works fine, if I load Aerial normally. But as soon as I try to lazy load it (e.g. by the means of any of these: cmd = "AerialToggle", event = "VimEnter", ...) it claims that there is no backend available for this first file. I need to open another file, then everything is running fine if I go back to the original file.

Could you please check if you can reproduce this bug? I'd really prefer lazy loading Aerial.

[EDIT] This behaviour happens with all filetypes I tested: Rust, Markdown, Python, Java. So, I guess that this is not filetype dependend.
