Float fails when in Terminal buffer

[Ian S. Pringle]

To reproduce:

1. :terminal<cr>
2. :lua require'lir.float'.toggle()
3. The opposite of profit

As best as I can tell, if you toggle a floating Lir window while in a terminal buffer, Lir will fail with the error

...lir/float/curdir_window.lua:98: attempt to index a ni value

In addition to this error in the command area, it shows Process exited 0 in the floating window. Upon exiting this window :q the "heading" window (smaller floating window above the larger floating window) remains up and will not go away until Neovim is exitted.

I discovered another issue that I cannot replicate but I believe might be tied to the above issue nonetheless:

Sometimes a buffer of Lir seems to "hang" in the background. For some reason this buffer cannot be killed and :q will not quit, due to this buffer being open. The only way to escape from this Neovim-jail is with a :quitall. There is a chance that this is unrelated to Lir, however it seems to only ever happen following the above error.
