fix(vscode): fix wrong squigglies on first load on Windows

dlltool, used when building with GCC-MinGW, has a bug which causes the
first call to napi_create_double to create 1.20305e-307 instead of the
intended number.

Work around this dll bug by making a dummy call to napi_create_double on
init to absorb the corruption.
