patch 9.1.0045: --remote-* does not ignore wilidignore

Problem:  --remote-silent applies the wildignore option
          to each argument, which may result in "E479: No match"
          (hebaronson)
Solution: temporarily reset 'wildignore' setting when building
          the :drop command

closes: #13835
