Subject: [PATCH] VS: Avoid empty, unreferenced solution folders... (#13571)

...in generated sub-directory sln files.

Thanks to rlandert for the bug report and proposed patch.

The method WriteTargetsToSolution gets called possibly multiple times,
once per sln file, (-> once per "project" command).

Before accumulating folder names in VisualStudioFolders, clear it
first, so it doesn't have stale entries in it from the previous
sln file.
