textDefinition on some comments returns an error

[simark]

This situation can happen if you hold ctrl down and hover some words in comments with your cursor.

client --> server: {"id": 124, "jsonrpc": "2.0", "method": "textDocument/definition", "params": {"textDocument": {"uri": "file:///home/emaisin/src/ls-interact/go-test/test.go"}, "position": {"character": 46, "line": 12}}}
server --> client: {"jsonrpc":"2.0","id":124,"error":{"code":-32600,"message":"Command failed: /home/emaisin/gopath/bin/godef -t -i -f /home/emaisin/src/ls-interact/go-test/test.go -o 334\ngodef: no identifier found\n","data":"Command failed: /home/emaisin/gopath/bin/godef -t -i -f /home/emaisin/src/ls-interact/go-test/test.go -o 334\ngodef: no identifier found\n"}}

In Theia, this results in an annoying error popup. If you move all over the comments with your cursor while holding ctrl, you'll get many error popups.

It can be reproduced when using this code there (test.go): https://github.com/simark/ls-interact/tree/master/go-test, and hovering the word "that" on line 13.
