Faceting with empty panels is broken for time series

[fabern]

Bug description

Similar to issue #50: when faceting and a panel is empty it leads to wrong grid lines and axis labels. While this works for a numeric x-axis, it does not when using DateTime as x-axis.

Steps to reproduce

using AlgebraOfGraphics, CairoMakie
using DataFrames, DataFramesMeta
using Dates

x = today() - Year(2) : Day(1) : today()
x = DateTime.(x)

y1 = cumsum(randn(length(x)))
y2 = cumsum(randn(length(x)))
z1 = cumsum(randn(length(x))) * 10
z2 = cumsum(randn(length(x))) * 10

dat = DataFrame(
    dates = repeat(x,4),
    variable = repeat(["y","z"], inner=length(x)*2, outer = 1),
    series   = repeat(["1","2"],     inner=length(x),   outer = 2),
    value    = [y1; y2; z1; z2])

# With all facets filled, labels and gridlines appear correct.
draw(data(dat) *
    mapping(
        :dates, :value,
        color = :series,
        col = :series, row   = :variable),
    axis = (width = 400, height = 225))

# With missing facets, gridlines (and labels) are wrong:
draw(data(@rsubset(dat, !(:variable == "y"  && :series == "2"))) *
    mapping(
        :dates, :value,
        color = :series,
        col = :series, row   = :variable),
    axis = (width = 400, height = 225))
draw(data(@rsubset(dat, !(:variable == "z"  && :series == "2"))) *
    mapping(
        :dates, :value,
        color = :series,
        col = :series, row   = :variable),
    axis = (width = 400, height = 225))
draw(data(@rsubset(dat, !(:variable == "z"  && :series == "2"))) *
    mapping(
        :dates, :value,
        color = :series,
        col = :series, row   = :variable),
    axis = (width = 400, height = 225),
    facet=(; linkxaxes=:minimal, linkyaxes=:minimal))
draw(data(@rsubset(dat, !(:variable == "z"  && :series == "2"))) *
    mapping(
        :dates, :value,
        color = :series,
        col = :series, row   = :variable),
    axis = (width = 400, height = 225),
    facet=(; linkxaxes=:none, linkyaxes=:none))

This works: Removing z2 gives wrong x-grid-lines and wrong axis labels (note that y-grid-lines are correct):

Unliking axes yields different grid-lines and axis labels as expected:
