Issue Description:
When I open a package directory in Visual Studio Code, the language server crashes immediately. If package was never built, or I delete the .build directory, the language server works perfectly.
Steps to reproduce:
$mkdir bug_report_package $cd bug_report_package $swift package init --type executable $swift run $code . click on main.swift file in VSCMore info about how I got here is in this thread: https://forums.swift.org/t/using-sourcekit-lsp-on-ubuntu-18-10/22598
