Debug assertion when opening some files with relative imports #291
Description
I wouldn't open this except that it fails in a debug build, which I assume means that it's a pretty unexpected error.
My environment:
macOS 10.14
VSCode 1.28.2
Python Extension, 2018.9.1, with trace logging enabled
A debug build of the python-language-server (mine's at 6d4659f)
Take the following archive: test.tar.gz and extract it somewhere (~/code). Open the folder (~/code/test) in VSCode, and then, as strange as this seems, use the explorer and open all the files in order, from the bottom up.
In other words, open util.py, main.py, lib/util.py, lib/test.py, and then lib/__init__.py. Then, observe the Python output window:

[Info - 1:24:51 PM] Connection to server got closed. Server will restart.
[Error - 1:24:51 PM] Request textDocument/documentSymbol failed.
A very cursory debugging seems to show that the lookup fails because the ModuleTable has an entry for 'lib.test' rather than 'test', but I don't know if that's actually the culprit, or if that's even a problem.
