tdf#139830: keep the right sidebar context for chart after view switch (calc).

There is a general behavior to switch to the default sidebar context
by view deactivation and switch back to the right context by view
activation. See SfxShell::Activate() and SfxShell::Deactivate().
By activation, we use the selection to find out the right sidebar
context. See GetContextForSelection_SC() method for example. However,
for charts, this does not work, because the chart window is a separate
environment and the shell does not know what is selected inside the
chart window. So let's avoid context switches when we have a chart
window active. Let the chart controller handle sidebar context changes.
