`createInstallTypingsRequest` has its own logic for extracting the
project root path from the project name and it disagrees with the
versions in the project flavors. In particular, it only drops the last
component of the name if it exists. For folder projects and JS-only
contexts, this will not be the case, but the last entry should still be
dropped.
TL;DR: stop creating filewatchers for
"c:/foo/foo.csproj*jscontent/node_modules"
Dynamic files are generally created by the debugger when while debugging
it can't find a matching file on disk. Since these files don't exist on
disk, we shouldn't check if the file exists on disk, and allow the content
to be controlled by the host.
