Apparently on older neovim versions, passing the name of script-local
functions to `timer_start` is not enough (in v0.10.2 this works, but
v0.7.2 not). Fix this by wrapping it in `function(...)` to pass a
Funcref.
See :h timer_start:
> timer_start({time}, {callback} [, {options}])
> [...]
> {callback} is the function to call. It can be the name of a function
> or a |Funcref|. [...]
