Remove unused variables

The LayoutManager for some reason has both a ToolbarLayoutManager
pointer field, and a uno::Reference to an aspect (or whatever term one
should use) of the same ToolbarLayoutManager. (I.e. esssentially two
fields for the same thing. Why it doesn't create such variables where
needed instead I don't know.)

Anyway, for some reason there were lots of instances where a local
variable was initialised with this second field but then never used. I
removed those. (Surely just copying the field into a local variable
doesn't have any interesting side effect that would explain this
pattern?)
