tdf#116511: Drop questionable check for more keyboard input

For some reason, on macOS, when this is being invoked through the
shortcut, Application::AnyInput( VclInputFlags::KEYBOARD ) returns
true, so the code thinks that there is more keyboard input and won't
call UpdateTokenArray(), which sets m_pTokenArray.

I think that optmisation is questionable, especially as the exact
semantics of our event loop API, like Application::AnyInput(), is
under-defined and probably can and will change in various minor ways
when people work on improving it on the Mac (and perhaps other
platforms, too).

(The event loop etc certainly needs improvement on the Mac. Consider
the "WindowServer grows to tens of gigabytes when running make check"
issue which is closely related. Unfortunately nobody has come up with
a simple fix for that yet, exactly because we use our event loop
related APIs in so imaginative ways all over the code, and fixing one
thing usually breaks another.)
