geom_glowpath() and *line() broken

[dominicroye]

I get an error when using geom_glowpath(). It is the same as in this example from the function help.

> ggplot(economics_long, aes(date, value01, colour = variable)) + geom_glowline()
Error in `geom_glowline()`:
! Problem while converting geom to grob.
ℹ Error occurred in the 1st layer.
Caused by error in `dapply()`:
! objeto 'single_value' no encontrado
Run `rlang::last_trace()` to see where the error occurred.

I have changed the ggshadow version from 0.0.5 to 0.0.4 to get the geom_glowpath() to work.
